We had an assignment about 3 weeks ago in my Fashion Jewelry class to work with P n' P (Press and Peel) etching. It's really easy, in theory haha. Just print on this special P n' P paper, iron on to your metal, use contact paper or paint pen to protect the metal you don't want etched, then submerge your metal in an acid bath. I use motherboard etching solution from Radio Shack. Wait about 3 hours, then wala! Your metal should be etched, now you can use it to make whatever you want. This was just a simple two finger ring I came up with after seeing this 1930's illustration of kids playing tug of war.
