These baskets are woven from the fibre extracted from sisal plants. Being very porous, sisal absorbs colour beautifully. The fibre is boiled with flowers, leaves or bark from local plants to give tarehe black, brown and yellow colours. Blue is derived from ink. Synthetic dyes are also used for brighter baskets. The fibre is twisted into string and then woven onto local grasses to form baskets. The process, from start to finish, is very time consuming (it can take +40 hours to make a basket), but the result is a beautiful product.
