Corduroy is a textile with a distinctively raised "cord" or wale texture. Modern corduroy is most commonly composed of tufted cords, sometimes exhibiting a channel between them. Both velvet and corduroy derive from fustian fabric. Corduroy looks as if it is made from multiple cords laid parallel to each other.

Velvet is a type of woven fabric with a dense, even pile that gives it a distinctive soft feel. By extension, the word velvety means "smooth like velvet". Historically, velvet was typically made from silk. Today, velvet can be made from silk, linen, cotton, wool, synthetic fibers, silk-cotton blends, or synthetic-natural fiber blends.
