I do use a thin batting behind the sections I'm quilting. Sometimes I put a lightweight mustin on the back of this so that it moves smoothly when I'm quilting, especially if I'm free motion quilting. Then I sew the sections together and put the fleece on the back, and connect the layers with several lines of in the ditch. The binding can be fleece carried to the front, or you can make it like a pillow case and turn it with no binding, simply stitching around the edge, or you can add a wider binding. I don't find it too easy to hand sew the binding to the fleece, so I machine sew the binding to the wrong/fleece side, and do the hand stitiching to the front/cotton side.
