The Nahua Indians of Guerrero, Mexico have the amazing skill of painting beautiful designs on paper made from the bark of trees.
Bark paper, or papel amate, is produced by hand in the state of Puebla by Otomi Indians using bark from the mulberry or fig trees. After the bark is washed, boiled, and laid in lines on a wooden board, the fibers are then beaten with a stone until they fuse together.
The Nahua Indians of southern Mexico have excelled for several generations at painting bright village and wildlife scenes on the hand-made paper.
