I am guilty of not liking what I have done, then rethinking and going at it again. I have gotten use to the idea of not planning a quilt out entirely, but just doing the parts I love the best , mounting it on the design wall and staring at it for a while. You have chosen a wonderful solution to the Blizzard of snowmen and it has turned out wonderful, creative and original. You should be proud to finish it and show it off.
