You’ll need:
Rope: At least 10.5 feet of 3/8″ diamond braid rope — about 4.5′ for the monkey fist knot and 3 feet (X2) for the braid on each end. It’s better to start with a much longer piece of rope, tie/position the monkey fist knot, and then trim off the long side. Also, forming the monkey first takes more rope (~6′), which is then tightened down to 4.5′.
Scissors or a sharp knife to cut the rope (Be carefull!)
Lighter to melt the rope ends, to prevent fraying.
