Let me tell you what a brown bag quilt is. A group of quilters....anywhere from 6 to 10 is good ...make a 12 1/2 block and put it in a brown grocery bag. If you have left over fabric you want to send along you stick it in the bag, if not , that's ok.
We picked every other Wednesday and traded bags and kept trading till each person had worked on each quilt top. I put fall colored fabric in with my block and ended up with a beautiful quilt. Brown bags are always fun. I believe some people call these Round Robin Quilts.
