Pernik It is typical for the masks worn in the region of Pernik that they are made of sheep and goat furs, wings and feathers, horns, corn leaves and hemp. Masks from other regions are usually made of cloth, wool, and parched plants. They are often decorated with beads and paper flowers. All masks are made by the persons who wear them or with the help of craftsmen known throughout the village for their skill. It is a long and complicated process. Shrouded in mystery, it is almost a ritual in its own right. http://www.carnaval.com/bulgaria/pernik-carnival.html
