Which is better and bunches less in the washer? I'm using terrycloth in my fleece right now, but I saw Joanne's has cotton batting which is supposed to be absorbent soft and scrunch free up to 10 inches. I've also heard of people using uhaul (what is that?) and puppy training pads (I've never seen any washable puppy pads) but I'm a little less confident about those. Has anyone on here used uhaul or cotton batting? Another consideration is thickness, since my sewing machine is with my mom and my friends machine is kinda.... it can barely take 2 layers of fleece and one layer of terrycloth.
