How do you fold triangle paper into ornaments for toys?

Fold the sharp corners under the fingers downward, open them and then fold the whole corner downwards, after folding, we pull the folded one open and fold it to the right, as shown in Figure 1. Then fold the remaining three corners inward along the crease. After the three corners are folded, turn them over and look at the three-dimensional triangle and fold it.

Process the orange color first, and fold the origami in half. Fold in half at the crease of the midline upwards again. The upper right corner is folded towards the 1 4 crease above the origami.

Fold in half toward the midline crease. The right side is folded to the middle, the bottom right is folded to the top left, and the marker point in the lower right corner is aligned with the upper edge of the origami.

Fold from the bottom left to the top right, noting that the bottom edge of the upper and lower layers of origami overlaps after folding. The upper layer of paper is folded down by the dotted line, pulling the origami outward. Continue folding, noting that the marker dots below align with the upper edge of the origami.

Press the shadow part into the lower layer of origami to complete one of the corners.

Prepare a square piece of paper, any size. Fold both sides in half to find the midline and back again, leaving the midline crease. Fold the two sides to the midline crease, fold the triangle on both sides with the midline as the side, a total of four small triangles, fold the triangle in half on both sides, and then open the fold your triangle, buckle the inside unchanged, open and flatten the excess, and then fold in half, half of the triangle inside is folded downward, fold out the pig's feet, and the other three are the same fold, according to the fold out of the pig's head and tail, draw the eyes, and a cute little pig comes out.

Cut out a square with yellow crepe paper, cut out several flower shapes with square crepe paper, bend the wire with pliers to make a hook shape, and pass the small petals through one end of the wire and glue them with double-sided tape. Then pass the small petals through one end of the wire and glue them with double-sided tape, and then pass the small petals through the end of the wire and glue them with double-sided tape to wear 13 to 15 flowers.

Paper stars are also girls' favorite toys, at that time I was very patient to fold a can, I haven't folded stars for many years, and I don't have the patience when I was a child. Paper pineapple is three-dimensional origami, it takes a lot of triangles to complete the paper pineapple, fold the triangle to be particularly patient, because this is not a fold can be done!

We fold the two middle lines of the confetti in half and open them, and turn the confetti to the back. Then we fold the four corners inward and then open them again, and then we fold the four corners towards the point under my finger, and press the crease with my finger below. The other corners are the same in turn.

Then we fold the crease of the paper a little more, and turn a sharp corner towards the left corner.

Four cutting methods. These are the four most common pre-attack plexus and the easiest way to cut.

1. Fold the sides in half: After aligning the two sides, press the folding line with a ruler and cut it!

2. Diagonal: Use the diagonal line to fold out two right-angled triangles of the same size, and use a ruler or scissors to tear or cut along the fold.

3. Middle line: The middle Zen leather line is folded, and the edges can be aligned with each other and then cut open.

4. Diagonal: Fold the corner line of Hui Ying and cut it according to the folding line.

1.Here we start with a double square fold, but we can also start with a double triangle fold.

2.Complete a triangular fold consisting of a valley fold, a mountain fold and a flat fold.

3.First a grain fold, and then.

4.Vertical valley folds.

5.A grain fold, then.

6.Here the 90° valley fold is done.

7.Press the direction of the arrow to open both layers and press at the same time.

8.All right! Complete the triangle folding.

II.1Fold with the triangular tip as the center point.

2. .Pull the end paper with the right hand to adjust the extrusion hole to a tight fit.

3.Fold the sides after filling in the whipped cream.

4.Fold inward in the middle.

5.Cut out the size of the hole as needed.

Prepare the tool yourself material: paper.

The specific tutorial is as follows:

Prepare a square piece of paper with two corners folded in pairs.

When the left and right corners are folded in half, they leave creases.

The left and right sides are folded to the source of the drink, and the upper corner is aligned.

A part is made.

Repeat the above steps, and we will need a total of three of these parts.

Take two socks and goose low-pins, and insert the two corners into the left and right sides of a corner.

Connect the third component according to the top edge connection.

A triangular piece of paper is made.

Expand your knowledge: Do's and don'ts of origami.

You have to do a lot of practice before you start experimenting with complex works.

Origami is based on geometry and mathematics, and considers and deals with the proportion, structure, color, shape, texture and other aspects of the work.

Triangle paper folding method, the specific operation method is to roll the triangle tip as the center point, pull the end paper with the right hand to adjust the extrusion hole to tighten, fold both sides after loading the padan fresh cream, fold it inward in the middle, and cut out the size of the hole as needed.

1.Fold with the triangular tip as the center point.

2. .Pull the end paper with the right hand to adjust the extrusion hole to a tight fit.

3.Fold the sides after filling in the whipped cream.

4.Fold inward in the middle.

5.Cut out the size of the hole as needed.

The triangular fold is not a complete work, but it is used in many origami, and we call it basic origami. I won't go into detail about them later. In the ** hunger of the future origami experience, the blue dotted line is the valley fold (folded forward), and the red dotted line is the mountain fold (folded backward), which will not be introduced one by one.

How to fold a three-dimensional triangle with paper is as follows:

First, the folding method

1. Prepare a square colored paper first, we fold the two middle lines of the colored paper in half and open it, and turn the colored paper to the back; Then fold the four corners inward and open them again; Let's fold the four corners towards the points under my fingers, press the creases with my fingers, and do the same with the other corners of the sedan chair;

2. Then we fold the crease of the colored paper again, and fold a sharp corner to the left corner; Then fold the sharp corners under the fingers downward, and then fold the whole corner down after opening; After folding, we pull the fold open and fold it to the right, and then fold the remaining three corners inward along the crease;

3. After the three corners are folded, turn over and see the three-dimensional triangle and fold it;

2. Three-dimensional triangle

1. The three-dimensional triangle is called a triangular pyramid. A type of triangular pyramid, geometric, consisting of four triangles. There is one vertex when the bottom face is fixed, and four vertices when the bottom face is not fixed. (A regular triangular pyramid is not the same as a regular tetrahedron, and a regular tetrahedron must be a regular triangle on each face);

2. A triangle is a closed figure composed of three line segments in the same plane that are not on the same straight line, which are connected sequentially and have applications in mathematics and architecture. The common spinnaker rubber shape is divided into ordinary triangles (the three sides are not equal), isosceles triangles (isosceles triangles with unequal waists and bottoms, isosceles triangles with equal waists and bottoms, that is, equilateral triangles);

3. According to the angle, there are right triangles, acute triangles, obtuse triangles, etc., among which acute triangles and obtuse triangles are collectively referred to as oblique triangles;

3. Expansion

1. Origami is an artistic activity that folds paper into various shapes; Origami is not limited to the use of paper. Origami enthusiasts around the world use a wide variety of materials while adhering to folding specifications, such as: tin foil, napkins, acetate sheets, etc.;

2. The combination of origami and natural science has not only become a teaching aid for the School of Architecture, but also developed origami geometry as a branch of modern geometry. Origami is both a toy and a mental activity; It is a symbol of peace and remembrance, as well as a form of pastime.
