I try to always use wide fabric for the back. But, I have learned to be very careful with the quality of the fabric though and open the fabric completely so I can see a single layer of the fabric. I first look for the color I want, then quality. Poor quality? I pass on the fabric even if the color is perfect. Just yesterday, I could not find the best color and ended up with 45" batik. It is lovely, perfect color but I will need to return to buy more becasue I did not calculate correctly and don;t have enough for the binding.
That seldom happens with the wide backs. Always enough leftovers for binding and a little bit of scrap to add to my stash.
