A bovine animal, Bos grunniens, native to the high plateaus and mountains of central Asia. The yak is covered the long, coarse guard hairs over a downy undercoat of fibers. The coarse fibers are used locally for carpets, blankets, sweaters, and outerwear. The fine down is similar to cashmere and is used for cloth and yarn.
A continuous strand of textile fibers created when a cluster of individual fibers are twisted together. These long yarns are used to create fabrics, either by knitting or weaving.
The entire back of a garment is one piece and has a single yoke superimposed on the outside.
Two identical pieces of fabric are joined to a shortened back piece to produce the total back.
The front and backs of a shirt are joined without a yoke facing.
