I keep coming back here, at least 5 yrs now, for a refresh before beginning the next project. I've been able to sew a canvas tent, canopy, sunwall(s) with vinyl window(s) and smaller projects like beach bags. Thank you so much for taking the time to teach these seams along with the tips & tricks provided.
I'm so glad to hear that my videos have been helpful to you over the years! It's amazing to see how far you've come with your sewing projects. Keep up the great work!
@SailriteDIY it is, and international too. I have a small business manufacturing shade ports and outdoor blinds. Way down on the Southern Tip of South Africa. I often take on unusual jobs, and your videos help me immensely. Thanks a million.
This is a great demo with very understandable instructions. I felt a bit intimidated by this task before viewing your video. Thank you so much for keeping it simple!!
Thank you so much. I "upgraded" my hobby from hand sewing to machine seeing and Im eager to make me a camping tent. Among the dozens of tutorials on YT, this is the most, to the point, clear and best explained one I saw. (No rambling,etc) SPECIALLY!, for the clarification of the characteristics and results of the diferent types of stitching (water resistance, etc.etc.)
Thank you ever so much. Every video I've seen on flat felled seams involves trimming one seam allowance and folding the other over it. I knew that just didn't seem right. I appreciate all of the info and the instructions for a proper flat felled seam.
You all probably dont give a damn but does anybody know of a tool to get back into an Instagram account?? I was dumb forgot my login password. I appreciate any help you can give me
@Roman Trenton I really appreciate your reply. I found the site through google and im in the hacking process now. Takes quite some time so I will reply here later with my results.
Well done! Your tutorial was easy to follow, along with an excellent rational of fabrics. I found you explained thoroughly different options of seam types and allowances for the particular project at hand. I also found you spoke clearly throughout your tutorial and it was easy to see what you were doing. Thank you for your video on how to construct seams.
Seamstick may build up on the needle, but usually the fabric cleans the needle as it enters and exits the fabric so it is not usually a problem with medium to heavy fabrics. If your using the seamstick or basting tape on lighter fabrics it may not clean the needle well and if the glue builds up on those lighter fabrics you can use a cotton ball with alcohol to clean the needle (usually needed only once per bobbin fill).
Does it help to use titanium needles on your machine? …I ordered some to try but unfortunately they haven’t arrived in time to do this project. I’ve got an industrial machine but it’s not a walking foot, so you have the advantage of not puckering 😜. Thanks so much for the video. So helpful. I’m in the UK, and have a narrow boat so need to do some sewing for that soon. This particular project is one for my work. …I’m doing outdoor seating cushions. Best wishes.
Spraying silicone on your needles, cone of thread, bobbin thread and tension mechanism will keep the seam tape from sticking as well as limiting thread breakage. This is a technique I have used for many years. BE ABSOLUTELY SURE TO HAVE GOOD VENTILATION!!! I usually do this with a large ventilator fan blowing to the exterior of my shop. Or you can spray and walk away for an hour and go have lunch, or do so just before leaving the shop for the evening. I confess I just spray and sew..I know not the best idea but honestly in canvas and upholstery work you will be coming into contact with many chemicals. Try to do so as wisely as possible. All industries have their own exposure risks.
@@johnettebeaver1991 Thanks for this 🙏🏻. Very useful to know. I’ve been curtain and blind making for almost 30 years, but mainly handmade things. …sewing this kind of thing always has me stumped 🫢. I use silicone on curtain tracks. It’s fantastic! Never would have thought about using it for this purpose.
Ahhh... that explains a lot to this beginner. Nailed the semi and full on the first try. I cheated and used tape on all folds because I'm still a newbie and need to concentrate on the stitching more than the holding. Oh, thanks for holding my hand and helping me re-time the LSZ1 last week. Thing runs like a watch.
This is probably the best video out there explaining these seams. I'm making a plain canvas sun shade for my sail boat to be used when pier side. It's 16 ft by 9 ft with a seam at the 8 ft center. I was at wit's end trying to figure out the best, strongest way to join the two canvas sheets, and the "flat felled seam" is the way to go. *This is how a "how to" video should be made.*
No ... Thank you! I finished the "awning" yesterday. It has a frame of ribs made from 1 inch fairing stringers and sprayed with tent seal. I'm an "over-kill" type so I put a zig-zag stitch down the 9 foot flat felled seam between the two straight stitches. I don't know if it makes the seam stronger but it looks "beefy" When this one succumbs to U.V. and oxidation I'll do the next one in "Sunbrella" Next project: zippered sleeve for my unprotected roller furled jib. ... more videos to watch! ;)
The double sided tape or seamstick can sometime get glue on the needle, but since the fabric is rather tick the needle is cleaned farily well everytime the needle enters and exits the fabric, so build up of glue is usually not an issue. The glue will not effect the bobbin or the hook of your sewing machine.
Thank you!!! Your videos are so helpful and so clear to understand and see what’s going on step by step. I have learned a lot in your videos thanks again!
@Morganmoonshine Since we are sewing Sunbrella Marine / Awning Grade fabric we are using a #20 needle (135 x 17 style for Ultrafeed #7010) with V-92 Polyester thread (#20204). However, if you do not have a heavy duty sewing machine you may want to use a #18 needle with V-69 Polyester thread (#20203).
I just watched a bunch of other videos that were almost an hour long. Mostly a wast of my time, people unprepared, "Oh wait I forgot something in the other room". What? MATT has great production values, consistency clear and gets the job done. Not hard to rewind to review, not a lot of filler chat. Great video!!!! You ought to do a how to on making the videos!!
Thank you for this, exactly what I needed, looks easy when someone who knows what they're talking about demonstrates the technique. Thank you again, much appreciated.
Great Video - BUT - I'm piecing 30" to a 60" piece - meaning the 30" would need to be to the right of my needle.........how can I manage that with a traditional sewing machine? or even with the one he is demonstrating.......there's only about 5" to the right in terms of space to put the fabric......help!
Wow a true professional. explained perfectly and confidently. Thank you for sharing your knowledge with me. I am making my own spray skirt for my canoe and will try the semi flat felled seam.
I ordered some waterproof canvas to line 2 chrome baskets that will go on top of my fridge. I don’t know how to sew, don’t have a sewing machine, and certainly not one capable of handling the fabric. As I never even earned my sewing badge as a cassette scout trying to make my girl scout shorts over 30 years ago, I’m not surprised.😂 Because this needs to be a quick project, will only be used to store and camouflage items stored in the baskets, I might simply duck tape the corners together. So, I hope you’ve had a good chuckle.😜
My patio chairs seat webbing was polyester canvas, grade I have no idea. I need to replace the webbing that ripped through in the center after exposure to sun and weather. It goes around and between the chairs two dowels, which is nothing like sling chairs as far as I can determine. I have bought Ottertex waterproof canvas to do the work and size 18 needles and upholstery thread that is supposed to be for "outdoors" use, for my Singer heavy duty 4452 machine. I have more than enough fabric and so believe that I should use the full flat felled stitch to do the job, as well as double up on the material to insure it's sturdy enough. My questions are; What size stitch would you recommend (using the S2 setting for doubling the stitch one time through seems ideal), Do you have any experience with the Singer heavy duty machines? Thanks so much, in advance , for your time and efforts to answer as well as for the informational video.
I almost always use the semi flat felled seam. I like having one unexposed stitch and I recommend #138 Polyester and Not #92 or if you don't mind spending more you could use Teflon thread which will never rot or damage due to UV rays. The full flat fell seam is stronger initially until the UVs get to it which could be 6-8 yrs with #138 polyester in California sunshine as an example. I find myself restitching #138 at approx the 8 yr mark enabling another 4-5 yrs before needing replacement.
What we show on the website is a very close up picture, so we can show you the weave of the fabric (kind of like the picture on a cereal box which has been enlarged to show texture). The Sunbrella fabric is rather smooth. You can order a fabric sample if you like at Sailrite.com.
Thank you for this video. I was going to make canvas covers for our patio chairs. Had no idea how to make the seams. I chose # 3 and it is working. I could not find the binding tape. JoAnne, I would have had to order it and it would take a week to get it. Wanted to make them now. Soooo, I use Gorilla mounting tape. It is an inch in width, but that was okay as I drew the 1/2 in line an just put the tape to the edge of piece one and piece 2 went along the 1/2 inch mark. Then folded the edge over it. My Viking 980q with a denim needle went through all of the layers. I had a little issue with the bobbin tension, but it had to do with how I was pushing the fabrinc through Thanks again for your video.
Great video. Are the procedures any different for very large panels? I'm making a cover for my canoe and the first step is sewing together two 4'+ by 15' panels and it would be great to have a seam where all the material stays to the left side of the needle rather then trying to bunch it up on the right side of the needle.
The flat seam is much easier to do on compound curves. Do you have any tricks to make such curves easier with the semi flat felled seam and the full flat felled seam?
Very educational for me. Please link your product recommendations, like the 3/8 seam sealer and such. I'll go to your website and see if I can find them. Have a blessed day
Hi Rhiannon, I have added the important products to the description, we are currently working to go back and add product links to older descriptions as it wasn't common practice for us back then. You may also click on the link in the main description and see the products featured on the right side of the blog on seam construction.
Sure I do, thank you! Do you have more info/sources for inquiry on seam strength with regard to different materials, say ripstop and dacron and x-ply? I found some info on SPI max (and how to count them in context) for (US) military parachutes depending on if straight stitches or two-step zigzag stitches are used; but nothing for tree-step zigzag for example, and I would strongly guess that this is only applicable for nylon ripstop and not dacron or x-ply.
Just viewed your video, excellent refresher for me. I do have a question for you though, was wondering why you don't use a double needle for last two seams rather than flipping and trying to have it come out straight in appearance. Is your machine unable to take a double needle?
Great video! I want to make a screen tent for camping. I read poly cotton is the latest trend for ideal tent fabric, combining the best of both worlds of cotton and polyester. Do you sell this type of durable yet breathable fabric that can be used for making a screen tent? Also, is the full flat felled seam better than an inverted seam for waterproofing tent?
We like to train our customers to use basting tape, endlessly consumable, highly profitable, quickly used basting tape.... lol. cant say they arent upfront about it
That’s not how I learned how to do a flat felled seam. How I was taught was to put the wrong sides of the fabric together. Prepare the seam for sewing as shown in the video from 8:08 to 8:45. This is where it’s different. Sew a line of stitches 1 inch in from the raw edge (1/2 inch in from the edge of the piece taped basted on top of it). Pull (or better yet iron) the seam open. Fold the wider part of the seam allowance to the left over the narrower allowance. Push (or iron) what you just folded to the left and sew a top stitch through the four layers close to the edge. You end up with a seam that has all the advantages of the two other methods shown - no exposed raw edges, esthetically only a single line of exposed stitches, and UV shielding on one line of stitches - plus it has greater strength.
Gazza-usa Here’s a video that shows a variation of the method I learned. The difference between the video and my method is that in the video one side of the seam allowance is trimmed after sewing the first line of stitches and in my method there is an offset in the seam allowance so trimming isn’t necessary. th-cam.com/video/KQ_JgFXhEaE/w-d-xo.html
OK, so in essence they are the same thing. In the video you provided she cuts off a bit of the overage to fold into the felled seam. In the video above, he positions it so that the overage is already spaced correctly and there’s no cutting. Above vide 8s more efficient in material and sunbrella is not cheap. Any savings are worth it. You are literally throwing dollars away if you cut off overages in sunbrella material.
+NoWorldOrder I like to break the seamstick rather than cutting it with scissors, by pulling it apart. I find it is easier to remove the wax paper doing this.
What is the best fabric to use for overhead canopy fabric in Los Angeles, California? I don't need super thick - would love for the sun to come thru a little bit. thx you
If it were me in California I would use Sunbrella Marine Grade or Awning Grade fabric. Here is a link: www.sailrite.com/Fabrics/Outdoor-Living-Fabric/Awning-and-Shade-Fabric/Brand/Sunbrella/Outdoor-Living-Use/Awnings
Thanks for the great video. Do you think this basting tape would work on a micro-fleece backed fabric? I'm specifically interested in its properties in helping to waterproof seams, but I don't have canvas fabric, I have a 3 ply waterproof fabric that has micro-fleece backing.
Hello sir, I don't know if you monitor the comment or not. Thanks so much for this video; learned a lot! However, I have one question. These seams seem easy to do, so as long as you are sewing in a straight line, however for some tarps and tents, it's necessary to do a curved seam, which complicates the process greatly. Any tips for doing a flat-felled seem with a curve to it? Fabric seems to bunch up a great deal when I attempt this...
We do have some videos showing sewing a semi-flat felled seam with a curve, but none showing a full flat-felled seam, since it is seldom used. The video showing the semi-flat felled seam is here: th-cam.com/video/ISiifXpZOXI/w-d-xo.html Starting at 2:30:00 is the best place to see how we baste and then sew the seam with the curve.
Usually when sewing medium to heavy fabrics the double sided tape does not build up on the needle. It can if you are sewing very light fabrics, but if it does you can clean it off with a cotton ball with rubbing alcohol on it.
I think something that would be really helpful for illustrating the construction of these seams would be an actual illustration showing an "end view" of all three seams side by side. I get it now that I've done a few flat felled ("double overlapped" in my mind) seams, but I had to watch a few times for it to sink in.
Sincere thanks, on your series of instructional videos. Working with cordura 1000 bag/pouch project (newbie here), and several of these videos has helped me procure the right materials and tools. Thanks again.
Yes a semi flat feld or full flat feld seam could be done on a curved corner as long as both fabric panels are cut to accommodate the curve. I would rather not spend the time on a full flat feld seam along a curve, but rather a semi flat feld seam as it is much easier.
how can you do that last seem on a large project? it looks like there has to be enough room from the needle to the back of the sewing machine for your fabric
I use sunbrella fabric. I sew a tarpaulin for the boat. But when it rains from the sewing holes, it drips water from the needle holes. I wonder which needle and what thread should I use.
Water will find its way through the needle hole. It often travels along the thread and wicks into the hole. Some say that a PTFE thread over a Polyester sewing thread will help prevent the water from soaking the thread and traveling down the needle hole. Why? PTFE thread does not soak up water. You can also use a "Seam Sealer" and coat the underside of the project to help keep water from leaking in holes. www.sailrite.com/Iosso-Seam-Sealer-4oz I hope this information is helpful.
Is it okay to put the seam sealer topside and underside? I put the seam sealer on the topside (outside) of canopy and felt like it wasn't enough as I did find a couple of drips during a light rain. You mention underside so that's what I'll do but is there a reason why? (sun exposure or it soaks in better?) ty!@@SailriteDIY
Out of curiousity, what kind of thread do you use and has it been UV treated. This would make a big difference to UV exposure and would be less of a concern. I’ve used the spray on UV treatment on canvas that repeals water. Very cheap and easy to do but make sure you do it away from the boat/etc that you are working on as it dries out on any surface and leaves a mark (which is waterproof!!!).
I am new to sewing and I want to make a canvas tarp for camping. The canvas material I got is only 5 feet wide and I need to sew another sheet on. Can it be done with a Brother ST 371 HD sewing machine or do I need to take it to a place that has an industrial sewing machine or should I just hand stitch it?
To determine if a home sewing machine can sew Sunbrella Marine Grade fabric (canvas fabric) perform this test: Cut up a pair of old blue jeans into four layers (not including the jean’s hems). Since a home sewing machine usually can’t handle a thread larger than v-69 use that thread size or something comparable and try to sew through the 4 layers of blue jean material. If it sews well and the stitch looks good on the top and bottom side of the assembly then chances are you can use your home sewing machine for that task. Remember if your home sewing machine can’t perform the above test you can get an Ultrafeed LS-1 for a little as $649. For more info click this link: www.sailrite.com/Sailrite-Ultrafeed-LS-1-BASIC-Walking-Foot-Sewing-Machine
You can check out our portable walking feet sewing machines here: www.sailrite.com/Sewing-Machines/Portable-Heavy-Duty-Sewing-Machines Or our Industrial Sewing Machines here: www.sailrite.com/Sewing-Machines/Industrial-Sewing-Machines
How is the last type more waterproof when the holes still go all the way through? I hear it in all the videos about this join, but cant understand why.
I was wondering the same thing. Then I realized before you sew the 2nd line of stitches, you stretch the fabric open. This means the fabric AND thread are under tension when the 2nd stitch is done. Once sewed, the fabric & sewing thread relax, collapsing back in on the holes. That makes it much more waterproof.
I keep coming back here, at least 5 yrs now, for a refresh before beginning the next project. I've been able to sew a canvas tent, canopy, sunwall(s) with vinyl window(s) and smaller projects like beach bags. Thank you so much for taking the time to teach these seams along with the tips & tricks provided.

Excellent guide. Just finished my first flat felled seams in heavy canvas with basting tape thanks to this.
Glad you like it! Let us know if you have any questions about our products or videos at www.sailrite.com
Excellenté! I'm " attempting " custom canvas cabana drapes for my patio. I'm using natural heavy canvas.
We are using the Sailrite Ultrafeed LSZ-1 sewing machine sold from sailrite.com it is part number 102600.
Great demo! I'm a professional seamstress and I was looking for a video that geared to industrial sewing. Love that basting tape! sold!
Great, let us know if you have any questions about our products at www.sailrite.com Thanks for your comment!
Thank you for this, exactly what I needed, looks easy when someone who knows what they're talking about demonstrates the technique. Thank you again, much appreciated.

+Richard Wessels Great! I hope it comes out well!
Great video! That's sewing in a nutshell and probably 90% of what we need to know about sewing.
Lol @ 4:57 This is the absolute truth. Sailright gives the hard sell on that basting tape no matter what kind of seam they're doing.
Thank you!...great video!
I learned more in 11 minutes than I could've imagined!
I get more and more confident with every video!
Great! Thanks!
Brilliantly demo'd & explained. Neatly sewn; love the stated cons and pros for each.
+Nancy Crome Thanks for your positive comments. Let us know if you have any questions.

JoAnne, I would have had to order it and it would take a week to get it. Wanted to make them now. Soooo, I use Gorilla mounting tape. It is an inch in width, but that was okay as I drew the 1/2 in line an just put the tape to the edge of piece one and piece 2 went along the 1/2 inch mark. Then folded the edge over it. My Viking 980q with a denim needle went through all of the layers. I had a little issue with the bobbin tension, but it had to do with how I was pushing the fabrinc through Thanks again for your video.
Very clear, helpful presentation of these three seam types.
Very professionally presented & narrated, excellent...
Thanks for the tips, what brand is the sewing machine that you are using?
Your welcome! Here is a link to that sewing machine type: www.sailrite.com/Sewing-Machines/Portable-Heavy-Duty-Sewing-Machines
That is correct, we do not sell double needle sewing machines and most of our customers do not own one. But, if they do, yes it should be used.
I know there are double needles but was unaware of a double needle sewing machine. Hmmmm...
Great video. Are the procedures any different for very large panels? I'm making a cover for my canoe and the first step is sewing together two 4'+ by 15' panels and it would be great to have a seam where all the material stays to the left side of the needle rather then trying to bunch it up on the right side of the needle.

Thank you so much. Great information and instructions
Excellent presentation and superb content. Carry on!!
The flat seam is much easier to do on compound curves. Do you have any tricks to make such curves easier with the semi flat felled seam and the full flat felled seam?
Great vid. Can you please do a vid demonstrating full flat felled zipper seams? Thank you
Very educational for me. Please link your product recommendations, like the 3/8 seam sealer and such. I'll go to your website and see if I can find them.
Have a blessed day
Hi Rhiannon, I have added the important products to the description, we are currently working to go back and add product links to older descriptions as it wasn't common practice for us back then. You may also click on the link in the main description and see the products featured on the right side of the blog on seam construction.
Great video with lots of good information. Like your Rolex man!
Nice explanations with regard to seam strength in relation to material!
Glad you liked it!
Sure I do, thank you!
Do you have more info/sources for inquiry on seam strength with regard to different materials, say ripstop and dacron and x-ply?
I found some info on SPI max (and how to count them in context) for (US) military parachutes depending on if straight stitches or two-step zigzag stitches are used; but nothing for tree-step zigzag for example, and I would strongly guess that this is only applicable for nylon ripstop and not dacron or x-ply.
Hi what sort of needle are you using as I keep having problems with glue pulling thread after sewing through the tape
Just viewed your video, excellent refresher for me. I do have a question for you though, was wondering why you don't use a double needle for last two seams rather than flipping and trying to have it come out straight in appearance. Is your machine unable to take a double needle?
Sorry what about the tape does it clog up the needle, also will a flatf felled seam cancel out the need for hemming.
good concise video, do you have any on sewing thermal bubble type insulation?
No, we don't, but I will keep that in mind for future videos.
How does a French seam compare to these? I like to add one on top of exposed seams as reinforcement and wear protection.
What needle and tension do you recommend for sewing heavy duty canvas on a standard homeowner's sewing machine? Thanks.
I recommend a size #20 needle and V-92 thread on an industrial sewing machine. However, for a home sewing machine I recommend #16 and V-69 thread.
Great video! I want to make a screen tent for camping. I read poly cotton is the latest trend for ideal tent fabric, combining the best of both worlds of cotton and polyester. Do you sell this type of durable yet breathable fabric that can be used for making a screen tent? Also, is the full flat felled seam better than an inverted seam for waterproofing tent?
We do not sell a Polyester/Cotton blended fabric for tents, sorry. Yes, a full flat felled seam is better, but it is also harder to make.
We like to train our customers to use basting tape, endlessly consumable, highly profitable, quickly used basting tape.... lol. cant say they arent upfront about it
Awesome video - thanks for posting!
Thanks!
That’s not how I learned how to do a flat felled seam. How I was taught was to put the wrong sides of the fabric together. Prepare the seam for sewing as shown in the video from 8:08 to 8:45. This is where it’s different. Sew a line of stitches 1 inch in from the raw edge (1/2 inch in from the edge of the piece taped basted on top of it). Pull (or better yet iron) the seam open. Fold the wider part of the seam allowance to the left over the narrower allowance. Push (or iron) what you just folded to the left and sew a top stitch through the four layers close to the edge. You end up with a seam that has all the advantages of the two other methods shown - no exposed raw edges, esthetically only a single line of exposed stitches, and UV shielding on one line of stitches - plus it has greater strength.
I think you are talking about a rolled hem. He correctly shows a flat felled seam.
Gazza-usa I’m definitely not talking about a rolled hem. A rolled hem finishes an edge; it does not join two pieces.
Gazza-usa Here’s a video that shows a variation of the method I learned. The difference between the video and my method is that in the video one side of the seam allowance is trimmed after sewing the first line of stitches and in my method there is an offset in the seam allowance so trimming isn’t necessary.

Thanks. Gonna check it out. The video above is how I leanrened, so anything new is great !!
OK, so in essence they are the same thing. In the video you provided she cuts off a bit of the overage to fold into the felled seam. In the video above, he positions it so that the overage is already spaced correctly and there’s no cutting. Above vide 8s more efficient in material and sunbrella is not cheap. Any savings are worth it. You are literally throwing dollars away if you cut off overages in sunbrella material.
Would you need to reverse the machine at the end of the stitch to lock it? I am just beginning. Lots to learn here
Yes, reversing at the beginning and end of a stitch is required.
Could you tell us the needle size and the thread size and type and part numbers used in the videos
It would be interesting to know what stitch length and thread and needle size ?
He placed the reply to another in the comments section here. You should read the information, if you have yet to discover it.
Great video, thanks! Is there a quick trick way to peel back the seamstick paper?
+NoWorldOrder I like to break the seamstick rather than cutting it with scissors, by pulling it apart. I find it is easier to remove the wax paper doing this.
What is the best fabric to use for overhead canopy fabric in Los Angeles, California? I don't need super thick - would love for the sun to come thru a little bit. thx you
If it were me in California I would use Sunbrella Marine Grade or Awning Grade fabric. Here is a link: www.sailrite.com/Fabrics/Outdoor-Living-Fabric/Awning-and-Shade-Fabric/Brand/Sunbrella/Outdoor-Living-Use/Awnings
Thank you, very informative.
Great vid and whats your machine?
Thanks for the great video. Do you think this basting tape would work on a micro-fleece backed fabric? I'm specifically interested in its properties in helping to waterproof seams, but I don't have canvas fabric, I have a 3 ply waterproof fabric that has micro-fleece backing.
I have never tried it on a micro-fleece fabric, sorry. It will require a test.
Hello sir, I don't know if you monitor the comment or not. Thanks so much for this video; learned a lot! However, I have one question. These seams seem easy to do, so as long as you are sewing in a straight line, however for some tarps and tents, it's necessary to do a curved seam, which complicates the process greatly. Any tips for doing a flat-felled seem with a curve to it? Fabric seems to bunch up a great deal when I attempt this...
We do have some videos showing sewing a semi-flat felled seam with a curve, but none showing a full flat-felled seam, since it is seldom used. The video showing the semi-flat felled seam is here: th-cam.com/video/ISiifXpZOXI/w-d-xo.html Starting at 2:30:00 is the best place to see how we baste and then sew the seam with the curve.
Will the tape stick to the needle on the sewing machine?
Usually when sewing medium to heavy fabrics the double sided tape does not build up on the needle. It can if you are sewing very light fabrics, but if it does you can clean it off with a cotton ball with rubbing alcohol on it.
At 8:53 : “ you can probably base that down “, does it mean that we can “ Iron it? “. Thanks, great video!
Yes, you can iron it on low heat.
Wonderfully done. Easily understood. Thank you.
Does that tape gum up the needle?
Excellent videos - clear and concise. Thanks very much!
I think something that would be really helpful for illustrating the construction of these seams would be an actual illustration showing an "end view" of all three seams side by side. I get it now that I've done a few flat felled ("double overlapped" in my mind) seams, but I had to watch a few times for it to sink in.
Great demo! Thank you!
Sincere thanks, on your series of instructional videos. Working with cordura 1000 bag/pouch project (newbie here), and several of these videos has helped me procure the right materials and tools. Thanks again.
+timapexdrums That is good news! Thanks for the positive comments.
Thank you! Very kind! 🙂
Glad you liked it.
Could the full flat feld seam be done on a curved corner? Or would there be too much extra to fold into the seam?
Yes a semi flat feld or full flat feld seam could be done on a curved corner as long as both fabric panels are cut to accommodate the curve. I would rather not spend the time on a full flat feld seam along a curve, but rather a semi flat feld seam as it is much easier.
Sailrite Gotcha. Thanks!
Which side of the vinyl do you use? Does it matter?
If the vinyl fabric is coated on both sides, it does not matter. If it is coated only one one side then the vinyl side faces the sun.
how can you do that last seem on a large project? it looks like there has to be enough room from the needle to the back of the sewing machine for your fabric
I use sunbrella fabric. I sew a tarpaulin for the boat. But when it rains from the sewing holes, it drips water from the needle holes. I wonder which needle and what thread should I use.
Water will find its way through the needle hole. It often travels along the thread and wicks into the hole. Some say that a PTFE thread over a Polyester sewing thread will help prevent the water from soaking the thread and traveling down the needle hole. Why? PTFE thread does not soak up water. You can also use a "Seam Sealer" and coat the underside of the project to help keep water from leaking in holes. www.sailrite.com/Iosso-Seam-Sealer-4oz I hope this information is helpful.
@@SailriteDIY thank you so much..
Is it okay to put the seam sealer topside and underside? I put the seam sealer on the topside (outside) of canopy and felt like it wasn't enough as I did find a couple of drips during a light rain. You mention underside so that's what I'll do but is there a reason why? (sun exposure or it soaks in better?) ty!@@SailriteDIY
Out of curiousity, what kind of thread do you use and has it been UV treated. This would make a big difference to UV exposure and would be less of a concern. I’ve used the spray on UV treatment on canvas that repeals water. Very cheap and easy to do but make sure you do it away from the boat/etc that you are working on as it dries out on any surface and leaves a mark (which is waterproof!!!).
I am new to sewing and I want to make a canvas tarp for camping. The canvas material I got is only 5 feet wide and I need to sew another sheet on. Can it be done with a Brother ST 371 HD sewing machine or do I need to take it to a place that has an industrial sewing machine or should I just hand stitch it?
To determine if a home sewing machine can sew Sunbrella Marine Grade fabric (canvas fabric) perform this test:
Cut up a pair of old blue jeans into four layers (not including the jean’s hems). Since a home sewing machine usually can’t handle a thread larger than v-69 use that thread size or something comparable and try to sew through the 4 layers of blue jean material. If it sews well and the stitch looks good on the top and bottom side of the assembly then chances are you can use your home sewing machine for that task.
Remember if your home sewing machine can’t perform the above test you can get an Ultrafeed LS-1 for a little as $649. For more info click this link: www.sailrite.com/Sailrite-Ultrafeed-LS-1-BASIC-Walking-Foot-Sewing-Machine

Hi, thankyou. I'm in Australia so haven't seen any sailrites for sale. They look great
You are welcome!
What type of thread and needle do I use. Emerald 118 machine.
How would you hand sew the full felled seam? I don’t have a machine
oh, never tried sewing by hand a full felled seam. I think it would take way too long to sew.
How is the last type more waterproof when the holes still go all the way through? I hear it in all the videos about this join, but cant understand why.
I was wondering the same thing. Then I realized before you sew the 2nd line of stitches, you stretch the fabric open. This means the fabric AND thread are under tension when the 2nd stitch is done. Once sewed, the fabric & sewing thread relax, collapsing back in on the holes. That makes it much more waterproof.
