National Intangible Cultural Heritage, Republic of Korea Yeomsaekjang refers to a craftsman who dyes cloth with natural pigments. Specifically, the art of dyeing, which has been designated as Important Intangible Cultural Heritage, involves dyeing with indigo. In the Joseon Dynasty, dyeing was a highly specialized skill such that a dyeing specialist was attached to the royal court. Natural dyes used for coloring cloth are plant, mineral, or animal matter, used as is or slightly processed. There are all kinds of dyes, but the indigo bush (Persicaria tinctoria) was the most difficult to use; the complicated dyeing process also required a high level of skill. With modernization as well as the introduction of chemical dyes, traditional dyeing has all but vanished. Thanks to a handful of dedicated craftsmen who have worked to revive the art since the 1970s, however, the art has been kept alive.

National Intangible Cultural Heritage, Republic of Korea Soban refers to a tray-table used for an individual or for a sacrificial rite for ancestors. Sobanjang means the skill of making a tray-table, or an artisan with such a skill. Murals in tombs of Goguryeo display many types of soban. According to records such as Samguk sagi (History of the Three Kingdoms) or Gyeongguk daejeon (National Code), there were state agencies responsible for production of dining tables. Soban production developed due to the preference for individual dining tables over those for two or more people under the influence of Confucianism, and due to the needs associated with large and small events, including wedding and sacrificial rites. There are 60-plus types of soban, depending on the place of origin, shape, and usage. Soban were chiefly made in Haeju (featuring engraved carvings), Naju (featuring wood strips with mid-level of legs), Tongyeong (featuring cloud-shaped legs), and Gangwon-do. The shapes of the soban legs differ from region to region; those made in Gyeongsang-do have bamboo-shaped legs, the ones made in Jeolla-do tiger foot-shaped legs, and the ones made in Gangwon-do and Gyeonggi-do dog foot-shaped legs.

National Intangible Cultural Heritage, Republic of Korea Naju Saetgollai refers to the work of cotton weaving or women cotton weavers in Saetgol, Naju, Jeollanam-do. Cotton was first introduced to the country by Mun Ik-jeom toward the end of the Goryeo Period (877-1394) from the Yuan Dynasty, China. Spreading throughout the country, cotton, together with rice, came to be used as a means of exchange from the early Joseon Period (1392-1910). The Japanese imported cotton from Korea. Cotton is produced through the following process: ginning, flattening cotton, spinning, deciding the density of warp threads, starching, and weaving. Cotton is harvested mid-August, with the first harvested batch usually the best in terms of quality. Cotton cloth produced in Gaeseong and Jinju used to be regarded as the best in the country; now, however, that produced in Naju has replaced it as the best one in the country.
