I love having a video tutorial on this link! I'm a longtime owner of this effect. I've owned this in
its print form for over 10 years. I did learn the special knot from the text and pictures. Though
over time I've forgotten the knot.
Now that I own the Penguin video I can easily relearn
the effect and special knot without trying to make sense of the intricacies of the knot from text.
Yay!
