Ottoman is a widthways-ribbed textile with pronounced, raised 'ribs' along its wale and course. Similar to grosgrain, Ottoman is known as a corded fabric, using a thicker yarn in the course rather than the wale to create raised stripes running across the width of the fabric.
Ottoman may be knitted or woven, and produces a stiff, heavyweight fabric; knitted Ottoman features a likewise widthways rib structure.[1] In knitting, the Ottoman rib pattern is knitted with double jersey machines. The rib lines in an Ottoman knit may vary in size from thin to coarse by adjusting yarn count and gauge.[2]
