Thonging

Thonging is a technique used in leathercraft and related trades that employs narrow strips of material, called thongs, to lace, secure, or decorate items. Common applications include belts, straps, sandals, harnesses, bags, and the edging of leather goods. The process typically involves marking a line of evenly spaced holes along an edge, punching or cutting the holes with a thonging chisel or pricking iron, and then weaving or knotting the thong material through the holes to hold parts together or create a decorative pattern.

Materials used for thongs include leather strips cut from the same hide, rawhide, sinew, or synthetic cords. The thong is usually waxed or treated to reduce wear and improve grip as it passes through holes. Patterns range from simple straight runs to cross-lacing or decorative braiding, chosen according to function and design. Thonging provides adjustable tension and a durable connection, while also allowing for repair or replacement of individual thongs without reworking the entire item.

In addition to leatherwork, similar lacing techniques are found in various textile and accessory crafts, where cords or straps are threaded through punched or stitched holes to join panels or secure components. The term is distinct from related notions of wearing a thong garment, which is a separate context outside the craft uses described here.
