Teacher Jana Mclain describes a piece of art at the Palacio Cortes Museum in Cuernavaca, Mexico. In this piece, two men are pictured separating cotton from a cactus. Evidence of cotton in the form of cloth and fragments of bloody fiber, interwoven with feathers and fur, has been found in Mexican caves dating back approximately 7,000 years. Today, cotton continues to be harvested and used in a wide variety of ways, from textile products to gunpowder, and from coffee filters to paper.
