2. Fold the square paper diagonally into an isosceles right triangle.

3. Fold the bottoms of both sides into acute angles, and press a crease at the midpoint of the bottom edge.

4. After the crease is pressed, unfold it.

5. Fold the right side (the side pressed by the finger) from the middle point, and fold to one third of the left waist.

6. Fold the left corner along the edge (at this time, there are two corners with the same size on both sides of the middle line. If it is not the same, it must be adjusted to the same. )

7. Overlap two equal corners along the edge.

8. See the two lines marked with a pencil? We cut along the diagonal, and the highest point cannot exceed the horizontal line.

9, open the corner below, the five-pointed star has been cut!

Methods and skills of paper-cutting;

First, fold

It is the most basic paper-cutting technique to produce repeated patterns after origami, and it is also a kind of expression technique adopted by monochrome paper-cutting. The different effects it produces depend on the number and angle of folding. When cutting flowers by this process, the paper can be folded for two or three times and then cut, and the pattern obtained is uniform on four or six sides. If you cut animals or people, the shape after folding once is symmetrical. Folding paper-cut is a symmetrical pattern, so the resulting graphics are more rhythmic. This technique is mostly used to cut happy flowers and ceiling flowers.

Second, yin and yang engraving

The basic effect of paper-cutting is achieved by using yin-yang lines alone or in combination.

Engraving, also known as carving, is a method of carving out the outline representing the structure of an object and expressing lines on a large block. This effect is thick and strong, with a strong sense of weight and a strong sense of contrast between black and white. The cut blank forms a pattern and the lines are not connected.

Male carving is also called carving, which is just the opposite of female carving, that is, carving the blank part and keeping the outline. The lines of the pattern are solid and the lines are connected. This method is smooth, clear and delicate.

The combination of yin and yang is the best paper-cutting performance. There are two engraving methods for the same work, yin and yang, which make the composition varied, and the black, white and gray in the picture form a sharp contrast. It is an expressive paper-cutting technique.

Third, perforation

Cut out the basic outline on the paper with a knife or scissors, and then punch holes in the pattern with a needle, mainly to connect multiple layers of paper, and at the same time see the fine in the rough. This technique is often used in embroidery patterns, and sometimes the patterns are symmetrical, such as pillow flowers, shoe flowers and sleeve flowers. 2 ~ 4 identical patterns are needed, so rice paper is often used for cutting, carving and punching, and then peeled off after completion, and multiple identical patterns will appear at the same time. Xuan paper is used because it is sticky and thin, and embroidery under it will not affect the aesthetic feeling. Instead, it is a quick and simple stapler and staple, which also plays the role of multi-layer paper connection.
