The difference between Woolen Spun and Worsted Spun
October 19, 2021
Woolen yarns are spun with the fibers going every which way. This causes the yarn to be light, airy with small fiber ends poking out. They are also warmer because of the airiness. Worsted yarns are spun with all the fibers aligned, making a smooth and dense yarn with more sheen and drape. Many commercial yarns are spun with the worsted style.
I once had it explained very simply: Woolen spun yarns are like bedhair in the morning - going every which way, and worsted spun are like hair after it's been combed.

Examples of Worsted Spun (not a complete list):
