A finishing process applied to newly woven rugs to give them an antique look, best known from Pakistani Peshawar (Chobi), Oushak and Kazak-style rugs. The freshly woven rug, darker at first, is stone-washed in what the trade calls an antique wash that softens the dyes, sometimes with chemical washing as well; it may also be left in strong sunlight and has its pile cut short, so it feels thin yet stays durable. Natural aging fades color gently and evenly down the pile, whereas a treated rug tends to look bleached and shows a sharp band of color in the middle of the fibers. Because such rugs are made to look worn, a worn look alone does not prove a rug is old.
