Material preparation: paper, scissors, pencils, etc.

Operating steps:

2, the triangle is folded in half.

3. fold it in half again.

5. Draw the pattern to be cut on it with a pencil.

6. The parts that need to be cut are indicated by shadows.

7. It looks like this after being cut with scissors.

More practices of window grilles are as follows:

1. Prepare a piece of red paper, preferably double-sided. In order to demonstrate the folding effect, I specially found a piece of paper, one side of which is red and about 20 cm square. Fold the red paper in half diagonally once, and be careful to flatten it. Because this paper-cut should be folded in multiple layers, each layer should be as strong as possible. Fold the folded paper in half along the center line so that two 45-degree angles overlap.

2. Fold the folded paper twice again along the center line, and continue to overlap the two 45-degree angles. Another fold is different from the last two times. This time, notice that one of the 45-degree angles is connected together, not spread out a few pages. Yes, it's in half. This time, the other side did not form an alliance.

3. Draw a pattern on the short side, as shown in the figure. Here is for everyone to see clearly, and the shaded part is drawn. In practice, as long as you can see the effect, you don't have to draw a ghost. You can cut off all the shadow parts with scissors along the underlined part.

1, the role of window grilles

Window grilles may be familiar to many people. Although modern windows have grilles, you can also put stick grilles on the windows yourself, which will make the windows more beautiful. Although window grilles are just decorations attached to windows, I have never seen that a good choice of window styles can improve the effect. So many people will stick grilles in the window, which will make the geomantic omen at home better, and it is also beneficial.

On the window, stick grilles can actually increase wealth, because from the perspective of geomantic omen, the window is the place where the outside atmosphere enters, and the window grilles can improve the air intake effect. Therefore, if you are in the window of stick grilles, you can make your own better.
