I volunteer to make quilts from double knit for homeless and nursing homes. We just cut up 9 inch squares and make two color quilts, 5 rows by 5 rows. Then put solid double knit on as backing, right sides together. Stitch around, leaving opening to turn right side out. Then just top stitch. You can tie every other block with yarn, if you wish. They are sturdy enough to last through years & years of washing at nursing homes. If you don't want to stitch them up, contact local quilt guild, they should know of some organizations that make blankets for shelters and such.
