How to Make a Ninja Star from Rectangular Paper

Take one piece of 8.5"x11" paper.

Fold the paper in half.

Cut the paper along the newly created crease mark.

Fold both papers "hot dog style". Repeat. You should have a smaller and funny rectangle.

Valley fold and unfold each element the other way.

Valley fold the bottom half to the right and upper half to the left at 45 degree angle to create a crease that ends at the middle crease. Repeat with the second paper.

Flip both papers over.

Valley fold both rectangular ends in half to create two squares. Repeat with the second paper.

Fold those squares in half diagonally bringing corners closer to center of paper and creating two triangles. Repeat with the second paper.

Fold those triangles across the center. Crease well and unfold. Repeat with the second paper.

Turn both papers over and put one on top of the other. The one on top should be vertical while the paper on the bottom should be horizontal and flat.

Fold the bottom triangle down on the top paper and do the same to the other side of the bottom paper. Do the same to the top paper now but tuck the square from the top into the pocket you just folded up on paper.

Your ninja star is finished and ready to throw.
