NOTE:
A plain weave does not necessarily result in a plain surface effect or plain design in the fabric, e.g. variation in the yarn counts warp to weft or throughout the warp or weft (or both) and variation of the thread spacing warp to weft can produce rib effects (see taffetta, poult, faille and grosgrain), while colour patterning of the warp or weft (or both) results in colour-and-weave effects.
