As odd as this may sound, I was commissioned to design some voodoo dolls for a friend of mine. The only problem I am having so far is designing the heads. He doesn't want the typical burlap sack heads. He wants them to look like they were carved from wood, clay, or stone.. They also must have a dark tone to them. Does anyone have any tips on how I can achieve this. Any ideas will be helpful. Questions, feel free to ask me!
