Corduroy is effectively a riged form of velvet. It is produced using twisted fibres, which when woven lie parallel to one another to produce this fabrics distinct pattern. The ridges in the cloth are referred to as wales. The number of wales in a inch determines the size of the cord e.g a standard cord is around 8 wale, while softer baby or needle cord will be around 16 wale. Corduroy is extremely durable and is used not only in dressmaking but also in soft furnishings and upholstery.
