I was overly optimistic. There was no crazy weekend sewing, just a steady three additional hours.
I'm still sewing the front of the binding on, then stitching the back side down separately. On the front of the stays the width of the binding around the edge is roughly the same as the width of the binding along the seams. It's wider in the back. If I was going to attach both at one time I would have to make them the same width. Next time.
