The difference between worsted-spun and woolen-spun yarns lies in how the fibre is supervised before the substantive spinning. The fibres of a worsted-spun yarn are first rectified straightened and then oriented in the same direction, this makes the yarn smooth and shiny, which gives your knitted fabric lots of stitch definition.
On other hand, Woollen Spun Yarn is not straightened. The individual fibres lie in each direction and create a yarn with lots of air pockets. This approach executes for a lofty, lightweight yarn that confines warmth. Woolen-spun yarns have a matte finish with a soft radiance and lend themselves well into extra-warm projects that will not weigh you down.
