Jeremy Shafer shows how to make flexible finger rings that look like reptilian claws by allowing joint movement. He also shows a handy way to maximize the number of squares you can make out of standard printer paper.
Each ring is folded from a 3-inch square and about 3 rings and one claw tip can fit on each finger, so in all it takes about 40 rings to adorn both hands. The paper I used in the intro is brown kami that I painted over with copper acrylic paint. I used gold acrylic paint on beige kami for the paper that I folded in the the tutorial.
