Making bast shoes (lapti), baskets, tussocks, birch-bark ware demanded special skills and mastery. Birch bark was harvested in the early spring in order to avoid hurting birch trunks. Then it would be cut into long stripes, flaked, oiled, and bound; only after that craftsmen would begin their work. Most often, birch-bark wickerwork was a male craft, because it required certain arm strength. Birch-bark goods were durable and waterproof. They were used for keeping salt and milk; the latter would not turn sour as birch bark is a good antiseptic.
