I buy full bolts of good quality muslin that is 90 or 120 inches wide for backs. I just love walking to my stash area knowing that I have a back already waiting for me. One of local quilt stores now is carrying a collection of prints in those widths. I got a white on white for a king sized quilt just recently but there were many other choices for other quilts in my future. Bottom line. if you can find what you like by the bolt, I would recommend buying it.
