Fat draw is the spinning technique used to create worsted yarns. It is spun from combed roving, slivers or wool top – anything with the fibers all lined up parallel to the yarn. It is generally spun from long stapled fibers. Short draw spun yarns are smooth, strong, sturdy yarns, and dense. Short draw spun yarns also tend to not be very elastic. These characteristics make them good for use in weaving. Short draw spinning is most often contrasted to the long draw technique used to spin woolen yarns.
