Discontinuous patterning techniques in Bhutanese weaving, using supplementary weft to create single-faced motifs and patterns (invisible on the reverse of the fabric), typically in the central field of a textile. They originate from Lhuentse in northeastern Bhutan and are used in ornate textiles like kushuthara, as well as others like aikapur, which are used for a variety of garments. Sapma is worked into the ground weave so as to appear flat, and is used to create block patterns resembling satin stitch embroidery. Thrima (Dzongkha for ‘coiling’), sometimes called tima, is much more intricate and laborious: pairs of extra weft threads are twined and interlaced with the warp to create dense, raised motifs that resemble cross-stitch and chain-stitch embroidery. It can be done across, along or diagonal to the warp, and is used for motifs such as geometric florals and auspicious Buddhist symbols such as the Tree of Life.
