Handmade Blue Zacualpa Table Runner. Approx. 60 x 18 inches. Beautiful Vivid Blue with woven decorative bands at the top, bottom and running along the sides. Fringes. Cotton. Fair Trade from our Guatemalan artisan cooperative. To make a Zacualpa Table Runner on a back-strap loom, the weaver starts with raw cotton that must be washed, combed and spun. She first stretches the long threads along a warping board to the desired length and attaches them firmly to her loom. Then she begins the complex process of weaving. To brocade, colored yarns are woven into the cloth to create the designs as the cloth itself is being woven. The weaver adjusts the tension of the loom by leaning forward or back because of the strap that fits around her back, hence the name "back-strap loom."
