I joined the Boomerang Earth 7.0 quilt block swap on the Quilting Board. There are 17 of us. Each one person sends a fat eight (11x18) of fabric to the other. In return they make a 12.5 inch block for you in the fabric you sent. I am making a blue one for the moderator as well. Mine will be for Quilts of Valor so I sent out red/blue patriotic fabric to each. These are the ones I have made so far.
