That is too big a mystery for me! What I don't like about mystery quilts is that I usually choose the wrong fabrics for the pattern. Even though my colors play well and look good together I find I would have liked the colors in opposite locations. I hope that makes sense. If I do a mystery quilt now-a-days it is with the idea that it is undoubtedly going to be a charity quilt anyway. Only then can I live with the disappointment with the results. Only once have I liked the results of a mystery quilt. The rest have been given away.
