I do swaps on this board. I like a little control...so I joined the one block/month which lists exactly what you want to get, and the boomerang - there we sent out the fabric and people sent back blocks. In boomerang we could also specify if we wanted certain colors, etc. I have loved both these swaps. I have not been disappointed at all. I like trying new blocks also, and this gives me the chance.
I wish the swaps were unwashed fabric, I don't like to prewash at all.
