Love the idea of the "undo button". You figure out how to make that work and you'll be a millionaire in no time. Lol!
Finally decided that if this was going to actually get finished and not end up in the UFO pile (think its down to about 15 or so now) I would just tie the center pieced area and SID around the borders. So several yards of tiny purple satin ribbon and a couple sore fingers later, it's done. Look in picture section for "Misty's peacock colors quilt". And I did finish the hand stitching of the opening from turning it.
