BKB: I hope Nilla won't mind my providing an answer. The main idea is you are given a general set of instructions about fabric color choices but that is all. Then in the following weeks, or months you are given instructions on steps to begin to construct your project. You are choosing fabric and constructing blocks that you have no idea how they are going to go together. Right now I am participating in one by "Paint me Judy", she has done six now with amazing results. The exact name doesn't come to mind but if you search under the Round Robin section you will see some that have "train ride" in the title, those are hers. Not knowing where you are going and having the quilt revealed a little every week is a whole lot of fun.
