It seems to be online. I saw it once, but I don’t know where to find it. I have done this before and learned from it. It’s hard to say. To make it simple, fold a red rope in half and twist it all the way around. After twisting a section, you can make a few figure eight knots. The figure eight knot is to lay both sides of the rope flat on your left hand, hold it with the thumb and index finger of your left hand, then use your right hand to pick up the rope in your arms and put it on the outside rope, and then pick up the outside rope. Go around the rope on top and go in from the bottom (a hole will be formed in the middle), pull the rope out and flatten it to form a figure eight knot. During this period, the left hand should be kept pressed and cannot be loosened. You can try it first. To twist a rope, you also need to hold the folded part with your left hand, the part where the two ends are connected, and then hold the two ropes with your right hand and twist them in one direction. Don't keep your hands far apart, about three centimeters, and twist it two or three times. Move your left hand to the position of your right hand, then move your right hand down three centimeters and twist.
