I can respond to the question as it relates to the Caribs in the West
Indies, but not South America. The Caribs make beautiful, tightly woven
baskets, and do rattan rugs, fern-root carvings, dugout canoes, coconut
carvings...some seed/bead work and wood carving...mostly they are known for
their basketry...they use native plants and dyes, which result in perfectly
formed baskets in natural hues.
By the way, the Caribs are dwindling in number. There are very few left. I
encountered them on the Island of Dominica...this island is a natural
wonder, and the people are friendly and interesting. The Caribs have a rich
and interesting history.
