No, never quit. Just keep on making those blocks and consider it a learning experience. We always see our own mistakes and not others, we are our worst critics. I feel that way sometimes at 'show and tell' at our guild meetings, some of those quilts are so gorgeous and I think I would never be able to make something so beautiful. Please don't throw in the towel on this, keep going and once it is finished, and quilted, you will love it and think of everything you will learn! Just my .02 worth.
