Iaido Sageo Knot

I am trying to learn how to tie a display knot on a Sageo for a sword’s saya. The Sageo is the hanging cord made of silk, cotton or leather that passes through a hole in the kurigata of a Japanese sword’s saya (or scabbard or sheath, which holds the blade of a sword).

There are many ways to wrap and tie a sageo on the saya for display. Does anyone have any resources they can share about how they learned to to tie?

This seems like one way to do it. Any others?
