I suggest you use a very heavy flannel for the backing and no batting. The flannel will help keep the quilt from sliding off of the bed, her lap or whatever. Be sure and preshrink the flannel. As for the label I would write it right on the back of the quilt with a permanent marker. If you make a mistake you can always applique a label over top of it. It might be a good idea to write the label on the back before you assemble the quilt in case the marker or pen bleeds through.
