Tuohi is the Finnish word for birch bark. So no surprise that’s the material Finn Tapio Anttila used for the Tuohi trays, which are manufactured using a hot pressing technique that evens out the bark’s surface irregularities, but still preserves each piece’s unique color and pattern. With birch, you can either use its white-based side or brown reverse; the trays are available in each. Interesting also that the bark can only be removed from the birch trunk around midsummer, so the exact annual demand must be known then and planned for ahead of time. Available at Showroom Finland.
