I just got done with a denim quilt using dark and light squares, low loft batting, and a flannel backing. The dark squares were pretty much all the same dark blue color and the light ones were of different tones of blue. For some reason its not as heavy as everyone said it was going to be...it was sure heavy when I was putting it together, but its almost as light as the flannel quilt I got with high loft batting (I think high loft batting).
