I don't do mystery quilts. I have a lot of severe chronic pain, so the time I have to quilt is very little. I have to know what I am making,because my quilting time is short. I don't want to waste my quilting time on a pattern I don't like.And to be honest, I don't use many patterns, I like to design my own. So,no, I don't make mystery quilts, but, if things were different and I wasn't in so much pain, I just might try one. Have fun if you do decide to make one.
