Hold the restraining rope in your left hand, and then wrap it around the hook, post or metal ring. The end of the rope should be on your right side.
Make a loop at the end of the restraining rope and pass it over the portion held in your left hand. The knot will resemble a circle with a line running through its center.
Slide the end of the rope behind the loop and itself, and then cross the loop in passing. Wrap your right hand below the knot and pull with the left hand. The knot will slip up to the object that you have tied it to, thereby providing a restraint.
