All good suggestions. I have used them all, except for donating them to a school. That is a good suggestion, too, but make sure the school wants the fabric, first. I make quilts for the homeless and lap robes for nursing home patients. I've used lots of double knits. I've even used larger pieces for the backing. put front and back right sides together nd stitch around the edges. Leave an opening large enough to turn right side out. Top stitch around the edges and tack (tie) in enough places to keep the two pieces together. Project completed. No batting needed.
