Tokyo fine-patterned dyeing (called Tokyo some komon in Japanese) is a stencil dyed textile produced in different wards of Tokyo like Shinjuku and Setagaya. It was designated as a traditional national craft in 1976. This textile can seem plain from afar, however, when examined up-close there are delicate geometric designs. This craft is a type of stencil dyeing that uses backing paper made through pasting together several sheets of traditional Japanese paper. An experienced carver meticulously cuts a pattern into the backing paper. Then, the process of handcoating starch on the textile is done by a dye artist.
