Took some work but RK Kilts might be interested in BAST

Bast are the strong fibers in the phloem of a number of dicotyledonous plants, in particular jute, hemp, flax, ramie, kenaf, roselle hemp, etc. They support the conductive cells of the phloem and provide strength to the stem. The bast of some plants are commercially important fiber crops. Bast fibers are often called skin fibers, since the fiber is extracted from the "skin" of the plant.
