Craft of making baskets and other containers with branches of trees and bushes.

National Intangible Cultural Heritage, Republic of Korea Wanchojang refers to an artisan with the skill of making objects with sedge (Cyperus exaltatus, wanggol in Korean), which is an annual/biennial plant that grows in a wet rice paddy or swamp. It grows to a height of 60 – 200cm. Sedge is used to make mats, seat cushions, and baskets. According to Samguk sagi (History of the Three Kingdoms), sedge was used during the Silla Period (circa 57 BC – 935 AD). During the Goryeo Period (877 – 1394), a sedge mat was laid on the place where the deities of the State are enshrined. Sedge mats were used chiefly in royal palaces, and they were also sent to China as gifts. During the Joseon Period (1392 – 1910), sedge mats were used mostly in royal palaces or in the homes of upper class people. In foreign trade, the mats made in Korea were regarded as luxury goods. Sedge products are made either manually or with tools. Mats and cushions are made either with a coarse weaving technique with warps exposed or with a close weaving technique with warps not exposed. As for the manual weaving method, eight warps are entwined to form a “井” shape and then two wefts are woven into it to make round or octagonal cushions and baskets. Production of sedge goods once went through the doldrums, but it regained strength in the 1970s and thereafter. Up to now, sedge has been used chiefly to make mats and baskets, but it can be used to make many other objects without the need for special tools by adjusting the colors and the thickness of warps and wefts.

National Intangible Cultural Heritage, Republic of Korea Chaesangjang refers to the skill of making a basket of diverse geometric patterns with thinly cut and colored bamboo skins, or to an artisan with such a skill. Colored bamboo baskets were loved by women at the Royal Court and of the noble class since the ancient period. Toward the late Joseon Period (1392 – 1910), they became popular items even for commoners as necessary articles for marriage. They were chiefly used to contain clothes, accessories, sewing supplies, and precious items. The first thing to do in making a bamboo basket is to peel off the bamboo skin in even thickness. The skin thus peeled is soaked in water and then trimmed, dyed, and spliced. The edges and corners are wrapped with blue or black satin silk. The designs made on the surface of a bamboo basket are mostly letters or patterns associated with propitiousness.
