  1. Wrap the rope around your hand twice, finishing the second turn near your thumb.
  2. Pick up the turn that's nearest your fingertips.
  3. Wrap that turn around the other two turns. It becomes the loop.
  4. Slide the knot off your hand and pull the loop and both ends to tighten.

Tip: It holds a load on the loop or between the two ends, and it's a safe way to isolate a damaged section of rope.

Try it now: Tie a butterfly in the middle of a phone charger cable or a dressing gown cord, then pull the ends and the loop in turn.
