How to fold the paper crane red envelope?

① Put one side of the paper up, and the paper facing up will eventually become the color of the paper crane. Then fold the upper and lower corners in half to the middle dot.

(2) Then continue to fold the upper and lower edges of the origami model to the midpoint on the basis of the previous folding.

③?

Rotate the origami model and fold the white point at the bottom of the origami model to the white point at the top of the origami model.

(4) Open the origami model after completion, and leave a horizontal crease after reduction and folding. Make two intersecting pre-creases according to the white dotted line on the paper.

Open the lower part of the origami model according to the pre-crease.

⑤ Fold the opened part inward and operate the right side of the origami model as well. Then fold the origami model according to the white arrow.

6. Pressure propagation is smooth,

Fold from bottom left to top right to form a crease. The right side of the origami model is also folded in the same way.

⑦ Open the triangular structure erected at the lower part of the origami model from the opening.

After flattening, a square structure can be obtained, much like the most important and commonly used square foundation origami.

⑧ Open the box at the bottom of the origami model. Fold the structure on the right side of the small square origami model below inward. The left side of the origami model is also folded inward in the same way.

Fold the left and right corners of the bottom of the origami model respectively according to the creases marked in the origami diagram.
