The backstrap loom is one of the oldest weaving technologies, used both in north and southern Philippines. The warp (lengthwise) threads are mounted on two beams: one elevated, usually on a house beam or a tree branch, and the other is harnessed to the weaver’s body with a backstrap. The weaver’s back provides the tension to facilitate the weaving process. Textiles produced by the backstrap loom are narrow, usually depending on the width of the weaver’s hips and the length of their arms.
