Signature blocks sound good, till you think about the magnitude of the whole thing. If we have 117 ?? participants, that means that we have to make another 117 blocks to give one to everyone. Wow, I am having trouble just getting around the 169 for the DJ. Then, comes the part of getting them to everyone. Do we have a central place to send all of them, and someone to get them all mailed back out? And people are making different sized blocks, so what size block would be used? Don't mean to be a wet blanket, but just throwing out some ideas. I don't back my quilts with cotton, so if I did this, I would end up with another whole quilt. Which is fine with me. I know that if we do it, I would use block A8, which to me is just screaming to be a signature block. I know that on mine, it will be my signature block. It was quick and easy. And there might be more farther into the quilt. I haven't looked.
