I have put together a small quilt and ready for the backing. BUT when the backing was cut at the store, I only have 4 1/2 inches extra. This would mean that I have 2 1/4 for 2 sides. Can the backing be pieced? My quilt top measures 22 3/4 x 27 3/4. Or can I just hope for the best and go for it???? This is my second quilt but the first was done 1987.
