1. First, fold the left and right sides neatly.

2. Unfold and fold the left side in, aligning the edge with the center line, that is, folding a crease that divides one quarter.

3. Expand it again and fold in the upper and lower left corners so that the upper edge of the triangle is aligned with the quarter crease line.

4. Flip it horizontally, fold the top quarter downwards, fold the bottom quarter upwards, and turn out the two triangles folded in step 3.

5. Expand again.

6. Fold in half from top to bottom.

7. Fold the folded top left and right corners downward so that the edge coincides with the one-quarter crease line.
