I have started buying the 108" quilt back fabric. In the long run it works out to be less expensive then buying 44" wide fabric especially when you find it on sale, and you usually don't have to piece it. Thousands of bolts regularly carries 108" wide backing fabric and Hancocks of Paducah is currently having a sale with many of them being $9 or $10 per yard. 2 1/2 yards at $10 per yard is only $25.00 as opposed to 9 yards of 44" wide at $4.95 if you managed to find a fabric that inexpensive works out to be $44.55
