Bacbac, the bark-like dried outer leaf sheath of the abaca tree, is also used for design and textural definition.
Raffia fiber has a density which translates into fabric with a polished, satin-like hand. The fiber is extracted by hand from the unopened leaf of the African Raffia (or Buri) Palm, a slow-growing, wild palm specie with very large, fan shaped leaves. The fibers, several feet long, are split into strands of differing dimensions, and hand-knotted prior to weaving.
