Blankets under the pinilian description are textiles woven with pre-selected warp threads that produce brocade weaves or designs appearing to float on the cloth’s surface. Pinilian also refers to the supplementary weft technique employed in textile weaving using either continuous or discontinuous supplementary weft yarns (Pastor-Roces, 1991). The use of discontinuous yarns is called inlaid, locally termed as insukit or inkaot in Ilocos (Respicio, 2014).

In this textile, the insukit or inkaot technique is used to produce arrangements of geometric-shaped motifs in indigo and red colors. According to Respicio and Yoshikawa-Zialcita (2020), designs woven in alternating colors are attainable because of this technique (p. 189). These designs also appear scattered on a plain ground weave or background of the blanket, as opposed to those made using continuous supplementary weft yarns, which appear as designs arranged in rows (Respicio, 2000). As part of the finishing touches, the blanket ends with fringed borders, locally known as pulikos.
