Funny. I have had that happen and yet when I kept on working on the quilt and saw the end product ... well, I loved it again.
I only gave up once. I bought the fabric for a OBW that would do so beautifully. Once I got it home the color seemed different. It reminded me of sick body fluids .... No way would it be a OBW. It did make a cute bowl that I gifted to a friend.
