A reef knot

How to tie a reef knot (also known as the square knot)

See below for Reef Knot video.

  • A reef knot is a binding knot used to hold things together, such as parcels or to tie a triangular bandage. It is a knot used with a single piece of rope and is not used to tie two different ropes together.
  • To extend the activity, a rope at least 2 metres long is useful, but a dressing gown cord will work.
  • Show the video demonstrating the reef knot; if it is not possible, demonstrate yourself. It's helpful to colour the ends of the ropes to identify which end goes where.
  • Can they tie the knot after a 5/10 minute break from memory?

Extension:

In pairs, each holding one end, can they tie a reef knot without letting go of the rope? One person should use their left hand, and one person should use their right. Swap hands.
