Thank you to the Fujimori family and Awagami staff for sharing this ancient process. Washi is made from the inner bark (bast fibre) of Kozo. After soaking, the outer bark is carefully scraped off. The remaining bast fibre is cooked with soda ash and then hand beaten. The pulp is added to a vat of water with the addition of nori. After vigorous mixing, sheets of paper are made on a bamboo "su".
