The Iban Dayaks are renowned for their ceremonial blankets known as pua kumbu. These impressive textiles are woven exclusively by women who gain high social standing by crafting ‘potent’ textiles for ceremonial use. The design on pua feature water serpents (nabau) a symbol of the underworld and stylized human figures with outstretched arms representing guardian ancestors. Designs with human figures are a specialty of the Saribas River area. According to Brigitte Khan Majlis (The Art of Indonesian Textiles, 2007), weaving of pua kumbu almost completely ceased with the onset of World War II due to the scarcity of material.
