Origami Eight-Point Throwing Star

Supplies

  • You will need eight square sheets of origami paper

Directions

  1. Begin by folding the first sheet of paper in half. Unfold the paper and fold the outer edges in to meet the center crease.

More Traditional Ninja Weapons

While many people are familiar with the throwing stars, traditional ninja weapons also include other styles and you can make origami versions of these as well. Try folding paper throwing knives and origami swords to add to your collection.

For Play or Display

If you're making paper ninja weapons to use as accessories for play, you can reinforce them with a layer of clear tape so they will last longer but still look great. Leave the tape out if you're planning only to display your models, however. With crisp, tight folds and good quality origami paper, your displayed ninja weapons will last for years.
