This is the first piece of Cholla Cactus that I've turned. It was cast in dark purple resin (not by me - picked this up on another forum). Kit is a Chrome Atrax Rollerball. CA finish. My wife and I both really like how this one turned out. (My wife loves checking out my pens as soon as they're finished. And, if they get her seal of approval, then I know I did good!)
