There are many different weights and sizes of woolen yarns. We shall need to know about only a few of these.
All yarns are made of twisted strands of thread. The weight depends upon the number and size of the strands that are twisted together.
If two strands are twisted together, the yarn is two-fold.
If three strands are twisted together, the yarn is three-fold.
If four strands are twisted together, the yarn is four-fold.
If you are uncertain of the “fold” of the yarn you have, untwist a little piece and count the strands.
