Simple method of folding ninja darts

The simple way to fold ninja darts is as follows:

1. Fold two square pieces of paper in half on the left and right respectively, and then open the paper after folding the center line. The edges on both sides of the midline are folded inward until the midline is aligned.

2. Fold two pieces of paper from top to bottom, fold the horizontal center line first and then open it.

3. Two pieces of paper are folded in opposite directions along the horizontal center line.

4. Turn the two pieces of paper over separately, and then fold the two ends inward into a Z-shape.

5. Overlap these two pieces of paper into a cross. After overlapping, insert each corner into the seam, and after all the pieces are inserted, the ninja dart is completed.

Like samurai's bushido, ninjas follow a special set of rules that they are proud of when they surrender. Ninja usually wears dark blue or purple clothes.
