Woven with 1 cm wide tape. Adorned with birch cubes, leather cord, and wooden beads. The entire process, from harvesting to processing, is done by myself using birch bark from Nagano Prefecture. As the amount harvested is small, I can't weave large baskets like those from Russia or Northern Europe, but I'm working hard to make them available at an affordable price. These coasters have a simple and warm atmosphere. They are resistant to moisture but vulnerable to dryness. Applying vegetable oil occasionally will help maintain their flexibility. As these are handmade by an amateur, there may be splinters, but I hope you will enjoy them as part of their character. Nordic goods Birch bark Russian crafts Eastern Europe
