I have made many charity quilts with a pieced top and fleece backing. They are warm and if used as a lap quilt for wheelchairs, etc., the fleece stays in place better than cotton backing. I put the top/back together and do plain line stitching every 6-8 inches. I start in the cernter and work to sides stitching about 3/4" in from all sides. I then use a scallop blade in my rotary cutter and cut all the way around. Gives a nice finished edge.
