When my Mom was confined to a wheelchair, I made a lap quilt & put ties on the top sides so the quilt wouldn't slide off her, but having the flannel on the back did keep it in place pretty good. One thing I added was a pocket that was "free" of the quilt. I took a piece about 15 x 6....hemmed all the edges....and then just folded up one end & edge stitched it.....I then sewed this into the top before adding the binding...(not a good explanation but hopefully you can picture it)
