Dadeumi

Dadeumi (Korean: 다듬이) or dadeumijil (다듬이질) is a Korean traditional ironing method where two women knelt on the floor, facing each other across a smoothing stone, beating out a rhythm on the cloth to press out its wrinkles and soften it. Dadeumi requires dadeumitbangmangi (다듬잇방망이) and dadeumitdol (다듬잇돌). The former is a bat that pounds on the cloth, and the latter is the stone under the cloth.

Also, the cloth is wrapped in a thick round bat, hongdukkae (홍두깨), and dadeumi is performed. It is used to trim a thin cloth, such as ramie fabric (모시; mosi) or silk.

Similar practices also existed elsewhere in Asia, including in Japan, where it is known as kinuta.
