Selvedge (or selvage) comes from the phrase "self-edge" which refers to the edge being finished by the loom instead of sewn together after weaving. Selvedge is the term commonly used to refer to denim that has been produced on a shuttle loom. Since the amount of fabric produced from a shuttle loom is significantly narrower than a projectile (wide) loom, the cotton consumption is higher and the manufacturing time required is greater. Our selvedge denim usually has a red thread running vertically down the cloth, this identifier is know as the selvedge ID. We use other selvedge fabrics, for example chambray, for shirts and other garments, which have different selvedge IDs.
