Hanger Help

Hello, I have been looking up hangers and have seen some on amazon/ebay. But I want to make it on my own. Does anyone know how to make a DIY Leg hanger? I am looking for super simple ways. Like rubber bands or something that a lot of people have laying around house. I have seen the Captain wench hanger I am looking for something way simpler. I am trying to replicate this picture I guess or something similar. Url

Thanks
