Ditto to Tartan, Coordinate colors to the front/top and the same for binding. I love, the extra wide and have been know to go to Yoder's in Shipshewana, Indiana just to get the backing for multiple quilts that is wide. I seldom piece the back. Just my personal quirk. I will manipulate the size of a baby quilt to fit on a 42" wide back. (Shhhh- don't tell any one.)
