I made my first mystery quilt a couple of years ago and enjoyed it so much. We were given the name of the designer but not much else, then we were told how much fabric to get and the best clue was make sure there is alot of contrast between the fabrics. Then once a week we would get more instructions I think it was for 4 weeks. It was great because there were so many of us doing it that the fabric choices and even the finished quilt was incredible and they looked so different. Many of the participants made more than one at the same time, some were scrappy but I didn't have the nerve to do that. I believe my first was a Deb Caffrey design and I think it's my avatar. I made 2 of the same design with different fabrics because people liked it as much as I did. If you have the opportunity to do one, you might like to give it a try. So much fun!!
