Step #1: Gather thy materials!
Get a piece of paper. Any shape or size will do. I would recommend a paper with a middle-range thickness. Too thick and the folds cannot be made precisely enough, but too thin and the finished claws will crumple upon contact with anything too solid.
Step #3: From triangle to claw!
Follow the directions in the picture. `Tis a little hard to explain, but here I go -- never mind. Just remember, on steps 1 to 3 in my drawing the paper matches up at the conclusion of step three, and each time you use the previous step to outline where you fold. There's really no good way to explain it. I couldn't understand it until my buddy did it in front of me...
The finished claw can now be sealed for strength! You can even paint it! I find that the claws look freaky with watercolor paint on them, which works well because they're paper!
