I design simple patterns or blocks from my leftover fabrics. Usually use these pieced areas on only 1/4 or 1/3 of the back, with the rest in two large uncut pieces. Here are a few pictures of my pieced backs. I almost always piece the back, because I like using up leftovers and I think it adds interest to the overall look of the quilt. I do try to use coordinating colors on the back with the front, even if they are not the exact same fabrics that I used on the front (but I do try to use at least a few of the front fabrics on the back to "tie" it together).
