Preparation material: square paper.

1, prepare a square piece of paper.

2. The four corners are folded to the middle respectively.

3. Fold each corner inward along the crease.

4. Fold the top and bottom in half.

5. Fold the top up. The reverse is also true.

6. After the two sides are folded, it looks like this.

7. Then open the upper layer upwards, fold the left and right corners upwards, and the reverse side is the same.

8. Fold the upper opening downward, and the reverse side is the same, to obtain the following shape.

9. Finally, open it from the middle and arrange it around, and it becomes a square box.

The process of making blind boxes and bags

Preparation material: square paper.

1. First, fold the square in half along the center, along a quarter of the origami, and both sides need to be folded symmetrically.

2. Then fold the two ends into a triangular crease in the middle, and fold them up and down separately in the same way before unfolding.

3. Fold the middle triangle inward in turn according to the way of folding the small triangle inward, and a sharp three-dimensional triangle is completed, and the other end is also folded into a sharp three-dimensional triangle in the same way.

4. Then fold another piece of paper into such a three-dimensional pointed triangle and overlap the two three-dimensional pointed triangles.

Finally, fold the remaining two pieces of paper into two three-dimensional pointed triangles and overlap them, and then everyone can use their creativity to cover the two boxes together.
