JD of Tying it all together, is the instructor. He has many instructional knot tying videos. This particular video is focused on tying a single strand ringbolt hitch, A.K.A. Coxcombing. This was a common knot used by sailors to decorate items and parts of their ship. However, actually creating this tie is much easier said than done.
1: Take three lines for making the coxcomb, about 4 times the circumference of the final product. You'll need extra to allow for small errors
2: Tie them into an overhand knot
3: Move the knotted end to the top and then work with a constrictor knot
4: Take any one of your knots and make a half-hitch or single hitch. It doesn't matter which direction.
4: Take any of the three and make a half-hitch or single hitch as shown... the direction is unimportant.
5: Bring your next line over the first and make a half-hitch in the opposite direction.
6: Make a half-hitch with the last line opposite of the last one you did.
7: Fair the hitches as you go
8: Make a half-hitch with the furthest line.
