I never make myself finish a quilt I'm hating. I Typicaly put it away with the pattern or notes or even just a picture and go on to something else more often than not I have either gone back to finish the problem child, or I get inspired to take it a different direction. Either way it's a finished project that I am happy with.
I am actully currently working on one of those problems I took it a differnt direction and I absolutly love it. There is still one child sitting in the corner it could possibly be there for a very long time it was not behaving well at all.
