My quilting guild has offered one for several years, and I finally did one this past year. It was a surprise at the end and I liked the end result. One woman organized it, and gave us fabric suggestions prior to buying fabrics. We met on a Saturday with our cut fabrics and were taken step by step through the project. Generally we finished a few parts of each step, then moved on to the next one. At the end the organizer showed us her finished quilt top and it made sense with all the pieces we had made. I finished it over the following week.
