I have never done a mystery quilt and probably never will. Like others, I have way too many quilts on my bucket list and I don't want to invest the time and fabric into a quilt I may not like at all when done. Heck I do that pretty well enough on my own with patterns where I know what the resulting quilt will look like but by not selecting quite the right colors/fabrics. I have never made a quilt using the line of fabric the designer created the pattern for either. But I have made them in fabrics that are very close to the colorway the designer used.
