This is a lesson in how to tie a ribbon in a perfect knot, which can be easily understood by focusing on your hands.
The basic way to tie a knot is the "square knot". When tying a furoshiki, start with this method.
If you tie it incorrectly, it will affect the shape of the ribbon you tie later. People who say, "I can't tie my sneaker laces neatly" are often doing this wrong.
While some people have mastered this knot naturally, it is a knot that is rarely re-learned. If you review the basics again, I think you will improve your bow tying skills dramatically.
Please enjoy the challenge together with Kokokuru Sensei.
