I got two sheets at the thrift store last year, they are stripped. I think one is about to become the back of ORL. I will cut and piece them in the quartered square layout from Missouri quilting videos. I have an idea for assembling front and back qayg all at the same time. I will have to wait for reveal to make sure. That layout is why I got the sheets in the first place, just hadn't "planned" on them as the back for the mystery quilt until now.
