Cut a square of paper, about 15 cm x 15 cm (or any size you prefer)
Fold the square in half diagonally to make a triangle
Fold the triangle in half again to make a smaller triangle
Fold the tip of the small triangle back toward the base to create a flap
Unfold once so you have a single crease guide for the tip position
Fold the paper so it forms a flat double-layer triangle shape along the guide
Fold one side corner of the triangle toward the center crease
Fold the other side corner toward the center crease
Fold the top flap down to lock the shape
Repeat the folding steps to create a second identical half
Place the two halves together so the folded edges align
Fold the combined piece along the center so it stays flat
Crease firmly along all edges
Trim any excess paper so the edges are sharp and symmetrical
Make 3–5 shuriken blades by repeating the whole process and matching sizes
Arrange blades evenly around the center point
Create a small center hub by folding a short strip of paper into a tight square/rectangle
Tape or glue the hub to secure all blades together
Reinforce the center with tape on both sides
Hold the shuriken by the center hub
Test gently first, then adjust folds if it’s too flexible
