I just put together a quilt top and it ended up 92". With the batting only 90 inches, my sister suggested -skip the binding and pull the excess around back. Works for me. No waste. And more important - I don't have to remove the lower and top border piece to take in the seams untill it is less than the 90". Originally, I planned to use the backing for binding. I resized the quilt from a pattern for a crib sized quilt. I was a little off with the math.
