Ribbon-like ribs

Grosgrain (, GROH-grayn, also sometimes pronounced , GRAHS-grayn), is a type of fabric or ribbon defined by the fact that its weft is heavier than its warp, creating prominent transverse ribs. It is called a "corded" fabric since the weft resembles a fine cord. [Source: Wikipedia ]
