A variety of baskets styles are created in different areas of Southern Zambia. These baskets are rustically woven and rooted in Tonga culture. All baskets are colored with natural vegetable dyes, or use no dyes at all, relying instead on natural contrasts in the weaving materials. Each type of basket is named according to the area from which it originates. Striking patterns are unique to each style of basket.
