Ribbonwork, the cutting and sewing of ribbons into geometric patterns, is practiced by various Plains Indian tribes, for example the Osage Nation of Oklahoma. The ribbonwork of the Osage is placed upon traditional clothing, generally worn today for ceremonial activities. Unfortunately, much of the meaning of the patterns and colors of ribbonwork has been lost due to the acculturation of the Osage tribe into more mainstream, Western culture. Today, ribbonwork has become a symbol of the Osage Nation and a marker of pride for its members. The material culture study of ribbonwork uncovers some of its traditional meanings and transformation over time.
