I recently made a denim scrappy quilt for a boys' charity and I used fleece for the backing, with no batting. I finished it by doing the "birthing" method, then topstitched about 1/2" from the edge all around and did minimal quilting, enough to keep the fleece from shifting. Thought it turned out just fine and it finished up very quickly. I used the "no-pill" fleece from Joanne's.
