How to fold the bookmark with paper is as follows:

1. Prepare a colorful origami with a square of 12*12 cm, fold the origami along its diagonal line and the middle line, fold the origami into a clear rice-shaped crease, fold the origami into a small square along the rice-shaped crease, and fold a right angle of the square outside the origami to the top of the origami.

2. Fold one corner to the edge of the other side and then fold it up. Tear off the rectangle at the bottom to get an isosceles right triangle. Fold up the two corners of the bottom. Open the folded graph and fold the top down. Fold the two corners up and stuff the excess part in the middle. Draw a square on the blue cardboard with a ruler and cut it out.

3. Unfold the origami so that you can see the creases clearly. Fold the origami along the creases in the previous step to the inside of the origami, rotate the origami by 18 degrees, fold the upper two corners of the origami to the left and right sides of the origami respectively, fold the surplus parts at the top of the two small triangles folded in the previous step out of Pikachu's ears, and fold the right angle at the bottom of the origami to the top.
