1, prepare a piece of red paper, preferably double-sided red, about 20 cm square.

2. Fold the red paper diagonally once and flatten it carefully. Because this paper-cut should be folded in multiple layers, each layer should be as strong as possible.

3. Fold the folded paper in half along the center line so that two 45-degree angles overlap.

4. Fold the paper twice along the center line and continue to overlap the two 45-degree angles.

5. Folding in half again is different from the previous two times. This time, one of the 45-degree angles (note that it is the side connected together, not the side scattered on several pages) is folded in half. This time, the other side did not form an alliance.

6. Draw a pattern on the shorter side. As long as you can see the effect, you don't need to draw a heavy shadow.

7. Cut off all shadow parts with scissors along the underlined part. Pay attention to cut slowly, it will be easy to cut if you are not careful. Also pay attention to the use of sharp scissors, because the paper is 16 layer folded and relatively thick.

8. After cutting, spread all the red paper. In this way, a beautiful paper-cut work-window cut was cut successfully. You can cut a few more. Be careful when using scissors
