I can get a king sized roll of batting, 120x120, of 80/20 at WalMart for $17.97. It's very similar to warm and natural, but just a bit of poly (shrinks less). I've used it in many quilts and love the way it works with FMQ, as well as how it looks after being washed....it has the crinkly look I want, but not too much. It also maintains the soft drape after washing.
