Merry Mayhem mystery quilts are great. I've been doing them for years and have made some patterns I would not have tried simply because I didn't know where it was going and I'm fairly decent at following instructions. Only once in all the years was I able to complete the quilt on New Year's Day and that was a real marathon of quilting. But, as my quilting skills slowly improve so does my ability to stay a bit more caught up until the reason I don't complete now is I don't marathon quilt. I have always been pleased with the result.
