Changhoji is a traditional Korean paper made from the bark of the mulberry tree. It is known for its durability and unique texture, making it suitable for various artistic and practical applications. The paper is often used in calligraphy, painting, and traditional crafts. The production of changhoji involves a meticulous process of harvesting, soaking, and beating the bark to create a fibrous pulp. This pulp is then spread out and dried to form sheets of paper. Changhoji is valued not only for its quality but also for its cultural significance in Korean heritage.
