How to make a three-dimensional handmade tree
How to make a three-dimensional handmade tree is as follows:

Materials and tools: color cards, templates, glue sticks, scissors.

1. Print the trunk template, ***4 pieces. 2. Glue the trunks together.

Make leaves. 4. Trees in autumn make maple leaves. After the trunk is finished, you can stick different leaves on the tree in the season you want to do.

Rainbow butterfly tree:

Materials and tools: colored paper, butterfly mold, white latex, scissors.

1. Draw the outline of the handle with a pencil and cut it for later use. 2. Then use a butterfly die press (also available in stationery stores) to press out butterflies of different colors on colored paper.

3. Cut green paper to make grass as shown below. 4. Apply white latex in the middle of the butterfly and paste it in the right place.

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.
