You could also use construction paper or cardstock to make a sturdier shuriken. If you already have square origami paper, use 2 sheets of that instead. [2] X Research source

Because both sheets are squares, it doesn’t matter which end you fold.

Both sheets of paper need to match perfectly.

Make sure the top and bottom edges line up so your crease is perfectly centered. The crease will form a point of reference to help you fold your shuriken evenly.

The folded part will extend past the horizontal strip. Make sure you crease the paper well so the folds are nice and tight.

The creases are important for allowing you to make edges on your finished shuriken.

Make sure the folded papers are centered so your shuriken is even.

You should have only 2 triangle ends sticking out.

Don’t throw the paper shuriken at somebody. The pointy ends could injure an eye.
