Say you have a bunch of billiard balls and a sh*tload of talent. Why not make a cool skull out of that billiard ball? Not just any ball, an 8 ball. This guy took an 8 ball and made it into a shiny skull. He makes it look so easy too. Just do this and carve this and voila! But it wouldn't be like this for all of us. My suggestion is go ahead and practice, practice, practice. I'm sure you know somebody with a pool table! They have 16 balls for you to practice on. If they're a true friend, they'll let you. Happy carving.
