Thank you, ladies! I have contacted One World Fabrics, yesterday, and they are not able to get any more of the 2012 Mystery patterns.
I will eagerly try a couple of the other places you have posted above, though.
OK, I just went to Stitch Publications who said for personal orders you need to go to Willow Lane Quilting Company. They don't have the 2012 MQ, either.
I understand that Quilt Mania must own the rights to this pattern and One World Fabrics told me that it is now out of print.
