In Sumba and West Timor, some weavers create patterns with supplementary warps, a technique called pahikung in Sumbanese and sotis in the Timorese Dawan language. In these techniques, extra warps float above several passes of the weft thread. Weaving with supplementary warps is a slow and difficult process. Timorese sotis rarely dominates a textile, but pahikung from East Sumba can cover entire panels with dense, intricate patterns. Pahikung cloths, which require meticulous weaving between selected yarns, demand greater skill on the loom than do ikat pieces. Aesthetic standards for these fabrics relate to pattern complexity and tight weave, revealing no loose or misplaced yarns in either the warp or weft of a completed cloth. Intricate raised motifs created by pahikung (or alternate weft) weaving reflect the time and craft involved in the rendering. Many highly valued Sumbanese fabrics combine ikat and pahikung techniques within one cloth, uniting two differently treated warps seamlessly by the same weft threads.
