back-strap loom
Quick Summary
The back-strap loom is a type of weaving instrument. It is a primitive variety of the two-bar loom, where one bar is secured to a stationary object like a tree, and the second bar is attached to the weaver's waist via a strap. This design allows the weaver to control the tension of the warp yarns by applying pressure as needed. This loom was utilized in pre-Columbian Peru, other parts of South America, and Asia.12
The fundamental principle of weaving involves interlacing warp (lengthwise) and weft (crosswise) threads to create fabric. Early looms, dating back to the 5th millennium BCE, used bars to hold parallel warp threads. A shuttle carried the weft thread through the warp. Over time, improvements like the heddle rod, which raised warp threads, and later the drawloom, enabled more intricate patterns.12
