Let's try to make a more beautiful and cool polyhedral origami 127

If you are confident in basic folding, try polyhedron origami!
If you are someone who has mastered or can perfectly fold basic origami such as flowers, cars, and animals and would like to try something new, try polyhedron origami.
It's a little more difficult than basic flat origami, but you can create new and wonderful pieces that you've never seen before.
It's perfect for friends who are confident with basic origami to move on to more advanced origami.
Unlike basic folding on a flat surface, the work is completed in three dimensions much more beautifully, and because you have to exert a high level of concentration throughout the folding process, the sense of accomplishment when you complete one is also great.


It's so brain stimulating that your head will feel dizzy when you finish it!
The polyhedrons in this book are completed by assembling a minimum of 3 units and up to 90 units.
Unlike regular origami, which involves folding a single sheet of paper, you must first fold multiple pieces of paper into units to complete a three-dimensional object.
Because they use their fingertips a lot while making multiple units, it's great for training fine motor skills and helping elementary school students develop perseverance.
Also, when assembling, you have to carefully consider not only the number of units, but also the color and shape of the units.
This is a task that requires a lot of brain power, so after completing one, your brain feels so stimulated that it feels like your head is spinning.
While making it, my concentration level is higher than ever.
You need to be able to quickly complete an accurate polyhedron without losing concentration.
Polyhedron origami is a great activity for brain development and concentration.

Origami that fosters interest in mathematics and a sense of geometry
The origami method introduced in this book was initially introduced in English-speaking countries as 'module origami' or 'unit origami', but was further developed into 'polyhedral origami' when it was introduced to Japan and linked to the study of mathematical shapes.
In fact, polyhedral origami is based on the basic shapes of regular polyhedrons, such as the tetrahedron, cube, etc.
The work is completed by placing the vertices on the triangular faces of each shape like mountains.
In this way, by doing polyhedral origami, you will not only become familiar with the structure of shapes, but also become interested in and understand mathematical concepts such as vertices, surfaces, and lines.


Decorate your special day or your room with the work you've created.
The completed polyhedron is so amazing and cool that most people who see it for the first time are very curious about how it was made.
Make a good polyhedron origami and show off your skills to your friends and family.
Even though the assembly method for this origami is the same, you can create an endless variety of works by using different paper colors.
You will also naturally learn how to arrange and combine colors.

Connect the pieces you like with thread and use them to decorate your room.
Wouldn't it be nice to decorate a tree or the surrounding area on special days like Christmas?
