Material preparation: red colored paper.

Operating steps:

1. Prepare a piece of red colored paper and fold the square colored paper into a rectangle along the middle.

2. Fold the rectangular colored paper to the left along the middle to form a square.

3. Open the newly folded colored paper, fold it diagonally into a triangle, and open it after folding one side. Fold the other side in the same way.

4. Fold the colored paper into the pattern as shown in the figure according to the crease left in the previous step.

5. After one side is folded, the other side is also folded, showing the picture effect.

6. After the fifth step is completed, turn the triangular colored paper upside down and fold the upper left corner down.

7. After the left side is folded, follow the same steps to fold the right side.

8. After step 7 is completed, turn the triangle upside down and fold the triangle down.

9. Note that in step 8, the triangle will be folded down beyond the bottom, as shown in the figure.

10, while the triangle part is folded down, attention should be paid to pressing out traces to facilitate later folding.

1 1. Lock the bottom with the small triangle in step 10 and fold it in half along the center line. After folding it in half, it is made into a butterfly after a little tidying.

Introduction to butterflies:
