Yarn‑dyed fabric means the yarns (warp, weft, or both) are dyed before weaving so colour runs through the structure, producing sharper, longer‑lasting stripes, checks, plaids, and textured effects compared with piece‑dyed cloth.  Yarn‑dying can be full (both warp and weft dyed) or half (only warp or weft dyed), and common dyeing methods include skein/hank, package, and beam dyeing.
