It is usually woven with a plain weave, twill or herringbone structure. Colour effects in the yarn may be obtained by mixing dyed wool before it is spun.

thumb|Mohair wool thumb|An Angora goat Mohair (pronounced ), originated from the Arabic word [مهير], is a fabric or yarn made from the hair of the Angora goat (not Angora wool from the fur of the Angora rabbit). Both durable and resilient, mohair is lustrous with high sheen, and is often blended to add these qualities to a textile. Mohair takes dye exceptionally well. It feels warm in winter due to excellent insulating properties, while moisture-wicking keeps it cool in summer. It is durable, naturally elastic, flame-resistant and crease-resistant. It is considered a luxury fiber, like cashmer
