How to Make an Origami Ninja Star: Easy Step-by-Step for Kids

Place one square sheet flat on the table. Fold it corner-to-corner on the diagonal, press the crease firmly, then open it back up to leave a clear center guide line.

Bring the two upper side edges inward so they meet neatly along the diagonal center line. Keep both sides even to form a clean kite shape.

Fold the top flaps inward again along the center line. This tightens the top into a sharper, slimmer point, so press the crease hard.

Fold the remaining lower outer edges inward toward the center crease. You should end up with a long, symmetrical diamond shape with clean, straight sides.

Fold the full diamond lengthwise along the original center crease. Flatten it into a narrow triangular module, making sure the edges stay aligned.

Bend the module across the middle at a slight angle to form one blade unit. Leave the pocket opening accessible, because that’s where the next piece will lock in.

Take a second prepared module and slide its pointed tip into the pocket of the first module. Push it in fully so the connection sits snug and flat.

Attach the third and fourth modules one at a time, alternating the colors as you go. Tuck each flap into the next pocket until the square center is fully woven together.

Press every joint flat, check that the points are even, and adjust the shape until it looks balanced. Show off the finished ninja star and give it a gentle spin or toss for the reveal.
