Oh, I so can relate to wanting the project to end with the front but since I am determined to not have UFOs around, I push on to the end. Therefore, backs are often pieced since I've scrounged around in my stash to find something appropriate. I have learned to stick with piecing that runs off the edges, though. Once I pieced huge squares, but then centering the front on those squares was a nightmare. I always keep in mind that just because there is a front and a back doesn't mean that the quilt will always fall front side up so I want the back to also be something I like. I'm happiest when the back is all the same fabric. :-)
