Welcome to our quilting family. As far as I know we aren't doing a pieced block exchange but there are several 4 or 6 inch square pieces of material that are being exchanged. What kind of block are you thinking of? If it is something that is not already being offered just start a new topic and I'm sure that you will get lots of takers. I think that it would be really neat to do a pieced block exchange. That way you could make a sampler quilt. I'm in if that is what you decide to do.
