Step 1: The First Folds
Start out by laying your paper down and making a diagonal fold so the top and side of the paper match up, this should create a right triangle with an extra long bottom. Then flip over the paper and fold the extra flap down so it matches up with the bottom of the triangle. Crease the fold with your finger nails, and move on to the next step.
Step 2: Making the Cuts
The procedure of neatly tearing the paper is simple. Fold, Crease, Lick, and Tear. Fold the paper, then crease the fold with your finger nails, lick the crease, flatten it out and tear it.
Use the instructions above to separate the triangle from the off-cut, this creates a perfect square. You should then fold the square in half and separate the halves. Now you have two halves of a square and are ready for the next step.
Step 3: The Rocket Ship
Take your two halves of the square and fold them in half BUT DO NOT TEAR. Arrange them so the creases are facing away from each other and the open ends are facing towards each other. Then fold the two tops inward so when you put them together it looks like a fat arrow. Then fold the bottoms the opposite direction so they look like the fins of a rocket, the entire thing should look like a 5 year olds representation of a space ship. check all your folds and move on to the next step.
Step 4: Making the Sssssnake
The first thing you do is to create the triangle, which is made by folding the body of one half so it matches up with the top and bottom of a half of the rocket ship. The picture below gives a good example of what it should look like.
Repeat this to the other half, mirror it.
Step 5: Germany
This step is a little tricky but gets easier with time, move on when you're done.
Step 6: Finishing Up
Fold a corner of the star into the opening on the opposite piece, repeat it on the same piece. Then flip it over and do the same.
You now have a paper ninja star, congrats!
