What are the toys that can be made from paper?

Paper darts:

Preparation materials: a 15cm*15cm square paper, paper cutter.

Step 1: Fold the square paper in half and divide it into two rectangles with a paper cutter.

Step 2: Fold the two rectangles in half.

Step 3: Take one of the folded rectangles and fold the corners of each end in the opposite direction (yellow); fold the corners of the other paper in the opposite direction to the corners of the first paper (blue).

Step 4: Take the yellow paper, pinch the triangle at the left end, and fold the right side of the paper to the left, using the corner at the closure as the top corner; fold the right end in the same way as the left.

Step 5: Fold the blue paper in the same way as in step four.

Step 6: Cross the yellow and blue papers (note that the side with the opening in the center faces out).

Step 7: Fold the corners of both ends of the yellow paper, then insert the corners into the opening in the center of the blue paper; turn the paper to the back and insert the blue corners into the yellow paper to secure it, and a four-cornered dart is folded.
