My friend recently taught me how to make Paper Ninja Stars, this is a slightly modified version of his.
You can double them to make them larger, and slightly better.
You can add tape or stickers to make it a little bit better also.
Step 1: Materials Used
The materials I used are:
Fold all edges into the center to make it look like the picture above...
Fold from left to right like the picture above.
Cut halfway off the top so that the point looks like this.
Staple in the middle, and repeat, then turn it sideways and staple once more, finishing off the Ninja star.
I am very bad at explaining steps.. Please do not judge by my explanations.
