I am doing one with my quilt guild right now. We are staying 24 inches and we have 5 of us. We are on the last row. It has been fun and fast. I have done three row robins with the guild and ended up with two king size quilts. One is a nice table cover. I am doing my row robin smaller. I hope to have it about 12-15 inches wide. Cannot wait to see it after the next meeting.
