[[101499|woollen fabric]] which is somewhat sharper to the touch, with striking twill ribbing. Typically in three-end warp [[100497|twill weave]]; in a heavier rendering in four-end reversible twill. Produced commonly from worsted yarns from sharper cheviot wool, in a one-colour or [[100715|melange]] rendering. Used for ladies' dresses, suits, trousers and skirts. The name is given by the Latin "serica" (= silk), although an alternative etymology is through the Spanish [[100000|erga]](= a light shawl or blanket).
