I have not done any swaps on the board, but it sounds like everyone is having great results, i did one in a guild and the blocks were horrible, i even got one scorched lol. I think i would like to do one with trading fabric as a starter, a small amount tho, possibly work up to blocks. I guess what is holding me back is having to make 12 blocks a month, if i am going to make that many i might as well put them together and have a quilt. but it does look, sound like fun.
