How to Make an origami Shuriken (ninja star)
Secure a square-shaped piece of paper preferably six inches long on both sides. Cut the square paper into two equal halves. Fold one piece longitudinally right at the middle. Open the fold and refold it horizontally, on the shorter side. Refold the longitudinal crease you made earlier. Then, fold both sides diagonally but facing opposite each other. Do the same steps for the second piece of paper except that you have to do the folds in the opposite way so that you create a mirror of the first piece of paper. Fold the rest of the square edges diagonally to have pointed corners. Insert the second paper onto the first one and then tuck all corners into the pockets that were created earlier. You now have a brand new shuriken origami!
