A Mystery Quilt is one that you don't see the final look until you're done. It's done in steps - some are sewn in one day with steps posted every hour - especially on days like New Years and the Super Bowl. For this one you pick up your next clue sheet on the first Tuesday of each month - for 6 months. The first one to come in with a completed top gets some kind of surprise. This is the first one I've been involved with and I'm not going to Google anything cause I don't want to spoil the surprise!
