Baniwa baskets, made from arumã fiber, are used to produce arumã lamps. Baniwa basketry is used by men and women of the Baniwa Indigenous people in agricultural activities, such as processing and storing food, making it part of the traditional agricultural system of the Rio Negro, recognized as Brazilian cultural heritage. Arumã fibers (Ischnosiphon spp) are extracted using techniques practiced by the Baniwa for millennia, and their coloring is done with natural dyes. In collaboration with +55 Design, the baskets are given a black color and new shapes to form a collection of lamps that showcase the creativity and skill of Baniwa artisans in innovating and celebrating their cultural heritage.
