The finished edge of a woven fabric that runs parallel to the lengthwise grain and prevents raveling. It is created during the weaving process when the weft yarn turns back on itself at the fabric edge.
From Middle English 'self-edge', literally meaning the edge that finishes itself. The spelling evolved through 'selvage' and sometimes 'selvedge', both referring to the self-finishing nature of this woven edge.
Denim enthusiasts prize selvage jeans because the selvage edge indicates the fabric was woven on traditional narrow looms, creating a denser, higher-quality fabric. You can spot authentic selvage denim by the colored thread woven into the edge - it's like a signature of the mill!
