I had one like that and finally finished it. Only took me 4 years. I would work on it, then put it back in the "todo" pile. My BFF saw it and fell in love with it, so now she has the monster and proudly uses it.
Your quilt is very nice and no one will know it wasn't met to be like you have it. My BFF didn't, and I was so ashamed of it I never talked to her about the "MONSTER".
Finish it and only you will know where the mistakes are hidden. :thumbup:
