It looks just like a Bento Box cut on the diagonal! Our small group met yesterday and we were discussing both D9P and Bento Box and the different ways the basic pattern could be cut and put back together to form a new pattern.
Each of us is trying to do a community quilt incorporating our stashes and those of the club to practice these patterns. Isn't it neat how such a simple pattern can become something else when it is twisted?
Nice job!
