The making of Andean textiles
Weaving in Andean cultures was usually done on backstrap looms made from a series of sturdy sticks supporting the warp, or skeletal threads, of the textile. A backstrap loom is tied to a post or tree at one end, while the other end is attached to a strap that passes around the back of the weaver. By leaning forward or tilting back, the weaver can adjust the tension on the warp threads as he or she passes the weft threads back and forth, creating the pattern that we see on the surface of the textile. By the time of the Inka, an incredible number of variations on this basic technique had created all kinds of textile patterns and weaves.
