I always said I was never going to do a mystery quilt. My Mom was in town for Thanksgiving and challenged me to do Bonnie Hunter's On Ringo Lake Mystery Quilt this year. I did have a lot of fun working along on it with the group even though I despise making the same units over and over and over and over again, however...I did not like the reveal. Way too much of one color...especially the color most of us thought was going to be a secondary color. I did stop making clues when units started getting pieced together in order to allow the most flexibility with switching things up at the end.
I have played around with a bazillion layouts, and viewed lots of peoples' variants but at the end of the day - this is one just not going to work for me. I will repurpose the parts into separate quilts.
But now I know for sure - Mystery quilts are 100% not for me. I might save the clues while a mystery is going on but I will wait until the reveal to decide whether or not to take the plunge.
