A distinctive group of Windochine textiles uses buntal fiber as the base material. Resembling a very fine, polished bamboo, this thin cylindrical filament is drawn from the leaf-stalk of the Buri palm. Woven buntal creates a two-directional fabric of polished finish and geometric refinement. It can be incorporated with other fibers such as knotted raffia for endless design and textural variations.

Lke other natural fibers, buntal is manually extracted, in this case by pulling individual fibrous materials from the Buri stalk; however, any given palm can only be harvested for one of its two distinctive fibers – either buntal, drawn from the stalk, or raffia, from the leaf – but not both. Top quality buntal approaches four feet in length.
