Kitsie ... For the QAYG that I've seen, that problem has been avoided, as the hand stitched strips were double folded, machine stitched on the open edge, and then your hand stitched edge is a folded edge, like it would be when binding a quilt. Clear as Mud? To me it would avoid the necessity of fiddling with that 1/4" fold back, and the fraying that ultimately might happen with the raw edge fold ... to say the least about the burned fingers! I know you have all all the strips cut already, but this might be a workable alternative, if what you figured out, doesn't continue to work! Or for another time.
