2. Fold the paper in half along the long side, then unfold it, then fold it in half along the long side, and also fold the other half to make the crease clear.
3. Fold the paper in half along the first crease, then fold the paper strip in half along the short side to form a certain angle, and fold it tightly to keep the paper V-shaped after it is released.
4. Cut a V-shaped opening at the top fold of the paper with scissors. Note that only one layer can be engraved.
Open the folded paper and show it to the audience. Cover the incision with your index finger when displaying. After the presentation, fold the paper as before.
6. Face the side of the paper without incision to the audience, and at the same time open the rubber band with your left thumb and forefinger, and take the paper under the rubber band.
7. Move the paper and hook the rubber band below with the V-shaped mouth. When you let go, the paper hangs on the rubber band. It looks like folding paper and hanging it on a rubber band, but the fact is that the cut on the paper hooks the rubber band.
8. Gently pull down the paper with your right hand, and the rubber band will be pulled down. When performing, you can slowly rub the rubber band with paper, then loosen it and slowly pull the paper down.
9. After the performance, remove or unfold the paper, smooth the V-shaped incision and hide it.
