As far as making the tree huggers. I took 30' of webbing and made 2 7.5' straps and 1 15' strap. Cut to length, burn the ends and tie a loop in one end and your done. No sewing needed. It holds me @ 245lbs. And yes there are videos on making whoopie slings on you tube. Use the force Evoex. Google, youtube and shut are your friends.
