No I don't. I am working on one right now that has 3 pieces. Now I did try a bit for it to conform to the front. The front is lots of tans and browns. The back is two pieces of dark brown with light tan between. From a distance it might look like an Oreo cookie.
I just don't get that exited about the backs because I am not making these to be judged by anyone. (I entered a show one time, and no more). They are to leave to my family. I have a system wherein they will draw numbers from a bowl and that will determine which quilt they will get. I want it to be fair.
