Tie a clove hitch to the vertical pole, below the cross pole.
Wrap the standing end of the rope around the running end. This is to secure the clove hitch from slipping around the pole and loosen the lashing from inside.
Bring the running end up over the cross pole; then round the vertical pole; and back down over the cross pole.
Pass the rope behind the vertical pole and back up in front of the cross pole, this completes the first wrapping.
Repeat the wrapping 2 times to make a total of 3 wrappings; pull each turn tight. Note: When the rope is wrapping around the vertical pole the rope should be to the inside of the previous wrapping turn.;
