My group is small (12) so last year we had a bag exchange. Everyone brought a grocery bag with a block in it and extra fabric. We exhanged bags once a month so every one took a turn making something in the other persons bag. At the end of 12 months we ended up with 12 quilt blocks to make a quilt with. some people even said you could add some of your own fabric to the project. We also did a row by row the same way.
