there are others that finish of the binding like this, you are not the only one. some days you need to do what works, lets hope that the pictures help you learn a different way, especially since you are not totally happy with that you are doing. Taking pictures along the way is easy, I tend to do it a lot anyway. I am getting good at it and it is good practice for me. I have a mystery quilt coming up on Sat that I need practice for. Though all the instructions are set for them. I am just proofing them at this point.
The hardest part is getting it the right length so it doesn't have a buckle or have to stretch to far over the space left for joining.
