Take two square sheets of paper
Fold each sheet in half lengthwise
Cut or tear along the fold to make two rectangles from each sheet
Fold each rectangle in half lengthwise again
Fold each long rectangle diagonally at one end to make a triangle-like flap
Fold the other end in the opposite direction so both ends are mirrored
Repeat with the second rectangle so you have two matching folded strips
Place one strip horizontally and the other vertically to form a plus shape
Tuck the ends of each strip into the folds of the other strip
Tighten the interlocking folds until the center is secure
Flatten the shape into a shuriken form
Adjust the points so they are even and symmetrical
