Selvedge is the (traditionally a red-and-white) stripe that you’ll see along the seam on the inside of old-fashioned jeans. More than just a fray – proof seam, selvedge represents a tradition, an attitude and era of craftsmanship. Here’s why we love it.
Technically, a selvedge (also called “self-edge” or “selvage”) is the edge of denim made on an old-fashioned loom. In the good old days before mass production, denim was made on fairly narrow 29 inch-wide looms by weaving a continuous string of cotton (the so called “weft” yarn) back and forth through the “warp” yarns. The selvedge is made when the weft yarn loops back; so the fabric cannot fray or unravel.
