The true flat felled seam is almost universally used for the ridge line of lightweight tents. For DIY sewers, it's a challenge to pull this off with slick 20d silicone coated fabrics!
I’m going to make a brushed satin robe for my mom. I want to try the flat felled seam with that. I just received the flat felled presser foot I ordered online that I’m excited to use. I need all the help I can get as I have only been sewing since August of 2023! Any advice would be greatly appreciated. 🦋
Me too! Its rarely used because of how complicated it is to do normally, but actually so simple with my double allowance trick, right?? If you do ever use it let me know how it goes!
Flat felled seams used to be on Levi's, back in the 70's and 80's. Now they use the Half flat felled; and other Jeans makers are not using them at all.
Hi Michael! Sewing this on a curve takes some practice, there are two ways depending on the nature of the curve. Before you cut, consider the curve and decide which you want to be the upper fabric (with one seam allowance) and lower (with double), because (at least) one of the panels will need notches cut into it because there will be less fabric to fill the same area due to the curve. If you aren't sure which, cut both panels with double allowance, lay them out, and you can physically see which will need to have the notches cut into it Method one is: 1 work out which parts of the seam allowance will be hidden inside and not visible from inside or outside the finished garment (answer: the seam allowance of the upper fabric and the second half of the double allowance of the lower fabric will be internal to the seam, if that makes sense) 2 cut notches in the unseen parts which will allow the fabric to move better in the ways you want it to. Do this by putting them together and working out what needs to have more give in it to allow it to go on the curve 3 sew the seam as directed in the video, ensuring you stay on the sewing line accurately (more important in this seam type than with a regular seam). This is where the practice is needed because it will be on your sewing skill to make it lie neat as you sew (the more curved the harder it is) Method two is: 1 put the two fabric panels together and work out where the notches need to be to allow the fabric to sit best when its a finished seam 2 cut ALL of the seam allowance (one on the upper and double allowance on the lower) with notches as appropriate 3 sew the seam as directed in the video The downside to method 2 is that the underside will have visible notches cut into it, but the upside is that it will be even easier to make a smooth looking seam in this way than in method 1. So for the hardest curves, you may want to do this Hope this helps! Keeping to the correct line when sewing is important on this because your stitch is also sewing into the seam allowance underneath, so that's the key to all of it (as well as making sure the fabric is behaving as you sew). Good luck with your sewing adventures!

love this. looking for a project to use this method.

Thank you
I am looking at this for camping stool seat seams at the corners for the tripod legs to be secured
Love this.
will the fabric be stiff?
How would you go about doing this on a curved to flat piece
Hi Michael! Sewing this on a curve takes some practice, there are two ways depending on the nature of the curve. Before you cut, consider the curve and decide which you want to be the upper fabric (with one seam allowance) and lower (with double), because (at least) one of the panels will need notches cut into it because there will be less fabric to fill the same area due to the curve.

3 sew the seam as directed in the video
The downside to method 2 is that the underside will have visible notches cut into it, but the upside is that it will be even easier to make a smooth looking seam in this way than in method 1. So for the hardest curves, you may want to do this

There is an easier way to do this with the same result
Thank you
