1. Bake the rope with fire. When it is hot, pull the silk out and rub it, and let it pass through the hole.
2. The rope ends pass through the pendant hole together, open the rope ends, tie a knot on the other side and then tie a knot on the other side.
3. Turn the knot upside down again, so that it is a positive and negative knot until the length of the rope head remains. The end is handled with a lighter.
