I've only done a couple that I machine sewed the back. I usually hand sew the binding down. However, on the second machine stitched (the first was a mess and took it out and hand stitched), what I did was attach binding to the front. Then I folded binding to the back, but I pinned on the front, in the ditch (parallel to the edge), really close together, making sure the pins were inside the edge of the binding on the back. I tacked the mitered corners in place, then sewed in the ditch on the front. I went pretty slow, but it turned out pretty good. By pinning close together, my binding didn't fold or creep like the first one I tried.
