I have used old towels in the past, I just fold them in half and roll them around the limbs and use good old duct tape. I have also used pool noodles, pipe foam insulation covers, and my favorite was 1" foam I bought at Wal Mart, it comes rolled up and sells for only 14.99. I am also contemplating old shoulder pads from a sports resale store for future monsters. Good Luck.
