Faille vs Ottoman

Faille and ottoman are the same idea at two scales: both are plain weaves with crosswise ribs, made by bending fine warp over heavier weft. The difference is rib size. Faille raises low, fine, closely spaced ribs for a soft horizontal grain; ottoman raises bold, rounded cords that stand in deep relief. One whispers a rib, the other shouts a cord.

Which to choose

Run a finger across the grain. Fine close ridges are faille; fat rounded cords you can feel individually are ottoman. They are points on one continuum of crosswise rib, with grosgrain ribbon sitting near the faille end.

Common questions

How are the crosswise ribs made?
By tension and yarn weight: many fine warp ends are set over a heavier weft, so the warp bends around the weft and the weft sits proud as a ridge. Bigger, heavier weft cords give bigger ribs, which is the whole difference between faille and ottoman.
Is grosgrain the same as faille?
Closely related. Grosgrain is essentially a firm, narrow faille, most familiar as ribbon; faille names the wider apparel cloth with the same fine crosswise rib.
