Abstract: The Cordillera region of northern Luzon in the Philippines is home to distinct ethnolinguistic groups who have a long history of producing textiles used in varied ways for clothing, rituals, and trade. One of these groups are the Itneg or Tingguian to refer to the “mountain people” found in the interiors of Abra in Cordillera, and in Ilocos Sur and Ilocos Norte, which are nearby provinces of Cordillera region. The Itneg are known for their textiles exhibiting repeating patterns and motifs. Blankets, primarily serve as ceremonial function in rituals such as weddings, funerals and wakes (Corditext Report, 2016; De Las Peñas & Salvador-Amores, 2016). This paper will focus on one of the Itneg textiles featuring the binakul pattern, where colored threads are arranged in the textile in the form of graduated rectangles emanating from a central rectangle to provide the illusion of movement.
Keywords: Binakul textiles, two-way twofold fabrics, symmetries, layer groups.
