Material: rope.
1. First find a line and fold it into two lines like this.
2. Hold the left end with your left hand.
3. Hold the two wires in the right hand and twist them in the same direction (same direction, that is, both wires are screwed up or down). At the same time, if the rope is screwed up, it should be screwed up from beginning to end.
4, rub a few times, and then let go of the left end, it will naturally roll together, like a twist.
5. Continue to hold the left end tightly and continue to twist the wire with the right hand.
6. Then continue to let go of the left end.
7. Just keep repeating until you want the length.
