Pull a piece between your hand, making an "M"
Twist the center piece once...
And then twice (there will be a little loop from twisting)
Take the bottom of the center piece up over your hand, and pull it trough the loop/twist (from back to front)
Pulling the center piece down will form a loop. Pull on the ends to tighten the knot
Sorry, it I'd hard to see the knot due to the black rope
