Shamans and elder women embroidered Duab Toj Siab onto baby carrier bands ( hlo hnab ) and jacket collars. Why? Because the pattern mimics a sacred mountain—a place where spirits cannot easily ascend.

The Vietnam War (called Tsov Rog by the Hmong) and the subsequent diaspora to the United States, France, Australia, and Canada radically altered the function of Duab Toj Siab.

The most powerful Duab Toj Siab pieces date from the late 1970s — after the Secret War in Laos. As Hmong refugees fled across the Mekong River into Thai camps like Ban Vinai, they carried little. But they carried needles and thread.
