How to fold stars on square paper?
How to fold stars on square paper is as follows:

Tool: long origami.

1, prepare a long note.

2. Tie the note in a knot.

3. Then tighten it bit by bit and fold it flat.

4. Fold the excess paper corners inward.

5. Fold the note in half again, just covering the corner of the paper.

6. Then turn it over and fold it in half. When it is folded to the end, put the note in the interlayer.

For children, origami games have many benefits. Origami can exercise the flexibility of children's fingers and develop their hands-on ability and innovation ability; Things in life, small animals, vehicles, etc. Become an image origami. In this process, children's spatial imagination will also be improved.

For the elderly, origami games can not only help them use their brains, activate their thinking, and achieve the overall coordination of the trinity of hands, eyes and brain, but also prevent the memory of the elderly from declining. Some sanatoriums use origami as a treatment for patients' rehabilitation.

The "origami mathematics" derived from origami art is proved by equations: theoretically, any geometric form can be simulated by origami. With the help of computer software aided design, today's origami researchers can fold more complicated graphics than before.

In Kamiya Satoshi, a 2m× 2m square paper was folded into a dragon, and its scales and claws were clearly visible. It is said that there are probably no more than 20 successful origami people in the world.

On the other hand, modern origami is not only an art, but also a new science: origami mathematics. It has been applied to the solar panels of artificial satellites, the storage methods of automobile airbags, and even the structural design of the Hubble Space Telescope, all with the help of origami mathematics.
