 Shuttle-loom-woven denim is typically recognizable by its "selvedge" (or "selvage"), the edge of a fabric created as a continuous cross-yarn (the weft) reverses direction at the edge side of the shuttle loom.The selvedge is traditionally accentuated with warp threads of one or more contrasting colors, which can serve as an identifying mark.Although quality denim can be made on either loom, selvedge denim has come to be associated with premium products since final production that showcases the selvedge requires greater care of assemblage.
