Using fleece for backing would save time and money for batting. The stores here have tons of fleece and always on sale.. Sew pillow case style and turn. Sew open end closed. Light quilting keeps both layers in place. Fleece is warm and durable. Perhaps you can get a girl scout troop involved in this service project. They can very quickly tie fleece blankets. Not the handmade with love quilts, but a lot less work.
