How do you tie a rope bridge?
To form the knot, run the end of the rope through the ring or around the post and hold the main part of the rope taut. Wrap the end over the main piece of rope, then bring the end through the loop you just formed. Now take the end under the main part of the rope, then down into the loop just formed by wrapping the end.
