Patricia Branstead, the master printer, papermaker, book artist and teacher of all paper-related skills under the sun, opened Kozo Fine Art Materials just so those of you who can spend an entire day in a paper shop would have something to do. The swinging poster frames in Kozo display an amazing array of handmade papers, from delicate, translucent white-on-white patterned Japanese Hakusen papers and semi-transparent Thai mulberry sheets to bark-pulp Nepali Lokta papers that come crinkled, tie-dyed, or embedded with leaves and flowers. Branstead offers $10-a-packet scrap assortments if you're having trouble confining yourself to just one pattern; the general art-supply section of the store also offers Charbonnel inks, printing plates, papermaking kits, gifts and much more. Set aside a day — or a week — to leaf through Kozo's stock.
