I made one with flannel and fleece on the back with cotton batting in the center. I would just as soon have left out the batting. the fleece kind of curls up- not as much left in the washer when you wash it. Be careful that you don't plug the drain! I took mine to a laundramat. Then my brother took it over, and now he wants me to make it bigger! I said WE can make it bigger... hee heee
