I use Sweat Shirt front and back for the backing of Charity lap quilts. I buy 1 for $2.00 or if I'm lucky and get there on their sale day, I buy 2 for $2.00. A man's unless very small will make the complete backing of a good slzed lap quilt by using the sleeves and piecing in strips. Another good thing about sweat shirts for charity lap quilts is that you don't need a filler.
