How sad that someone would be that rude and unkind. I'm with you - I wouldn't step a foot in that place again and certainly not recommend them to anyone. There are an untold number of excellent quilters on here that would be so happy to assist you in correcting your problem. Never mind the colors. Everyone has their own choice. We don't all wear the same color clothing, etc. Just hang in there and send a picture of the blocks and get some really good advice from here.
