I haven't read all the posts, just the first few, but could you post a picture, maybe some of us have the fabric and can help you replace the bad cuts? Or do you have some other fabric that is close to the colors that you could cut to make new 4-patches?
Don't give up, we're here to encourage you ~ we've all had disasters, somehow, someway. Sometimes the frustration quilts become our favorite cherished quilts :) Hang in there!
