Lily Jade - Backpack Straps Anchor Tutorial/Hints

It has taken me a while to discover my favourite and easiest way to attach the messenger strap onto the back d-rings of my Lily Jade bags to allow the bag to be worn backpack style.
There are several different methods out there, but this is my way of doing it. I hope that this helps anyone who is struggling with getting the strap anchored or who is looking perhaps for a different method.
