Origami How to Make Paper Weapons
Grab the bottom piece and fold it to the left, like picture 9. Flip it over again(pic 10). Take the that last unfolded piece on the right and fold it up so it looks just like picture 11. Now take that left side(indicated by the arrow in pic 11) and fold it over to the right; because there is already a line there, it should want to fold to the right spot. Now it looks like picture 12(minus the green arrow...). Grab that piece on the right and fold it inwards, picture 12 shows exactly what to do.
Now if everything has gone according to plan, you should have something like picture 13. Alright, great, time to do it again... but wait, this time do it the opposite direction. What do I mean by that? Well, on your second sheet of paper, go through steps 1-5 just as the pictures show. But, when you get to picture six, fold the corner the opposite direction. Continue in this fashion, using the same instructions as last time, only opposite. For example, when you reach picture 11, that triangle on the left will be on the right... just like picture14.
Now take that new piece(on the right in pic 14), flip it over and lay it on the other piece horizontally(pic 15). Tuck the top corner(highlighted in green under the flap and tuck the other corner(highlighted in yellow) in it's corner. In picture 16, the corners are still highlighted so you know where to put them.
Now flip it over and again tuck the corners into the flaps, picture 17 shows exactly what to do. And now you should have a perfect origami dragon... er, Shuriken. I'm getting confused.
