So for those who never press their binding in half -- are you still stitching through two layers of the binding for the classic double binding? Or are you advocating a single layer binding?
I'm having a hard time envisioning what the benefits are, but then, I don't generally have any trouble with my current method (I'm another who uses 2 1/4 inch strips, miter pieced, folded and pressed in half and stitched with a walking foot.)
