Hiapo is the barkcloth of Niue, beaten from the inner bark of the paper-mulberry tree and painted freehand in dark brown ink by Niuean women. In the fine 1880s style, painters worked in very thin lines, pressing ponga (fern) fronds onto the cloth as rubbed guides and building dense concentric circles, spirals and diminishing radiating motifs across the tan bark ground.

Many surviving hiapo carry handwritten family and place names inscribed among the medallions, turning each cloth into a genealogical document as much as a textile. This design system renders that tradition at its authentic aged reading: a warm mid tan-brown ground carrying an intricate spider-web of dark brown line, never bleached to cream or paper white.
