Difficulty: Moderately Challenging
Step1
Take the end (working end) of the rope and pass it up through the ring from back to front.
Step2
Take the end of the rope behind the long standing part (this forms a half hitch). Then bring it across the front of the half-hitch.
Step3
Now double back on yourself and take the working end of the rope behind the half-hitch.
Step4
Bring the end of the rope around to the front of the knot and pass it through the half-hitch.
Step5
Pass it all the way through and then pull on the standing part to secure the knot.
Step6
To tighten the knot pull on the long standing part (the bit we didn't use) and the working end (the short bit that did all the running about).
