Wrap the end of rope around the main strand one complete turn and poke its end through the hole.
Pull the slack through to form a single-strand figure-eight knot. There should be about two feet of slack between the figure eight and the end of the rope.
Trace the end of rope back along the exact path of the figure eight, starting with the side closest to your harness and finishing with the strand that emerges on the side away from your body.
Pull the knot tight and neaten it up. The figure eight follow-through should have two strands of rope that run exactly parallel through the bends of the knot.
Tie a keeper knot with the 6- to 10-inch tail that sprouts out of the knot away from your body to stop the figure eight follow-through from unraveling while climbing.
