The easiest step to fold a paper crane.

Preparation materials/tools: square colored paper.

Step 1: Fold the square colored paper diagonally once to get a triangle, and then fold it once along the center line of the triangle.

Step 2: Open the folded triangle, place it at right angles based on the center line of the triangle, put your finger into the triangle and press it down to get a square, as shown in the figure below, and open another triangle into a square in the same way.

Step 3: Fold one of the squares in half on the diagonal, as shown.

Step 4: Fold the inward-turned wings down and turn them based on the center line and the vertices on the left and right sides, as shown in the figure; Do the same thing on the other side.

Step 5: Fold up two unconnected wings, as shown in the figure.

Step 6: Make a paper crane mouth, as shown in the figure.

Step 7: Pull the left and right wings of the paper crane outward to deform the paper crane's body, as shown in the figure.
