I understand your frustration, after all, sale or no sale you paid hard-earned money for this fabric. However, I cannot for the life of me see the problem. It looks like the fabric has not been ironed and I can't tell what may be shadows from wrinkling and the fading you are talking about. I say cut it up and use it anyway. Just use it for relatively small
pieces of the block pattern...certainly not borders if it is that obvious. And don't go around telling everybody who sees this gorgeous quilt, let them ooh and ahh over the beautiful hand-dyed fabrics! Only your buddies here need to know the truth.
