How to fold the darts hidden weapons?

The folding method of darts hidden weapons is as follows:

1. Prepare two pieces of square cardboard. Fold in half vertically and horizontally neatly, crease and unfold. The upper and lower edges of the square are aligned with the middle crease.

2. Then fold it in half, and so does the other one.

There is a crease line in the middle of the strip, which will fold both sides in opposite directions. Another folded cardboard is folded in the same way.

4. Fold the rest of the folded graph into a small triangle and fold it up for alignment. Use the same folding method on the other side of the figure.

5. Finally, unfold the folded triangle. Two pieces of cardboard overlap neatly. Fold the triangle clockwise. The last triangle is pressed in the bottom gap and the dart is folded.
