I was late getting my quilt ready for a quilt show and the morning it was to be delivered for hanging, my hanging sleeve was still to be put on. I was in a total panic and thought if I could just sew it by machine I would make it on time. Instead of the hem stitch I used a zigzag and loosened the tension. It worked and popped out flat. I did not tell and no one ever knew. I made on time and early.
