Guess I am in the minority on this one. I always use a wide backing fabric. I don't like to piece the backs, and with so many choices in wide backing fabrics there is usually one out there to go with the front. Recently though I have purchase two different wide backing fabrics from Fabric.com @ $6.98 a yard. A neutral and a gold. So far they look great on all quilts I have finished. I like to save my left over pieces from all my quilts to make scrappy quilts such as log cabins, courthouse steps and the like. That is just my preference.
