ok so I take the green rope (one end has a loop and the other has a knot tied in it) adn put it around a tree and thread the knotted end through the looped end? Then I tak the prusic knot and put it on the knotted end so the knotted end won't come out of the loop? If thats the case then I got it. I pulled this harness out, never bene used and it was like trying to figure out one of those puzzles you see at the cracker barrel
