Black Ink - Thai Mulberry Paper - Roll - Unbleached - 37in.x32.5ft. - Mulberry paper is environmentally friendly, produced from the bark of the mulberry tree. The bark is peeled every 9-12 months, and regenerates without having to cut the trees down to make the paper. The machine-made mulberry papers are 100% kozo, a fiber which creates strong, smooth and flexible paper. It is available bleached (white) and unbleached (natural) and is excellent for woodblock prints, silkscreen, drawing, matting, and bookbinding.
