I have pieced a lot of backs - one specific was a MLB quilt for my daughter - I wanted to use the SD Padres fabric for the back but it was about 8 inches shy of being wide enough, so instead of going back and getting more fabric I used the fabric that was used on the front for the border and binding - it looked like planned racing stripes. (Not to mention it used up some of the leftover fabric instead of going into the scrap bin.)
