In addition, there are:

Step 1: Then fold the triangle in half again and spread it out.

Step 2: Then fold the four corners of the unfolded square paper towards the center.

Step 3: Turn it around after folding. Continue with the same steps as above, and fold the corners around to the center.

Step 4: Fold along the center line after folding.

Step 5: then spread the four parts, and you will be done.

Step 6: Then you can write or draw the contents of the game on it.

Step 7: If you fold the beautiful southeast and northwest, you can draw patterns with different colors of colored pens, which will look better.

Another way to fold the four corners is as follows:

Two pieces of paper can be folded into four squares and become "four corners". Two or more people hit each other's four corners on the ground with their own four corners in turn, and win each other's four corners by knocking them over. When I was a child, many people would tear up old books and make up many corners to play with.

First of all, we need to prepare the tool materials: two rectangular origami.

Step 1, fold the rectangular paper in pairs, and fold it neatly as much as possible, so that the finished product can be more beautiful.

Step 2: Two pieces of paper are placed in a cross shape.

Step 3: Fold each corner into a triangle with the same direction.

Step 4: Each triangle should be folded inward and pressed down in turn.

Step 5, the last corner should be inserted inside.
