Bark paper called amate is produced by hand in Puebla, Mexico by the Otomi Indians using bark from mulberry or fig trees. The bark is boiled and soaked until soft, then pounded with a stone tool until the fibers fuse into a flat sheet. The paper is used by Nahua Indians in southern Mexico who have excelled at painting scenes of villages and wildlife. It is also used by artisans in Guerrero who paint depictions of everyday life, animals, and flowers on the handmade bark paper.
