My finished troll-fang necklace. it's made out of air-dry clay and paitned with acrylic paint in ivory, and with spots of brown (and on the bottom, a dried blood shade from red and deep brown) drybrushed onto it to look like spots of decay. The top of the tooth is sculpted to curve in like the hollow of a tooth, and painted darker to add to the effect. The string is green and brown braided craft string. The tooth's about four inches long.
