Many times we are asked the question, "What does worsted yarn mean?" It's a good question! There are several thicknesses of yarn, which we refer to as weight.
Don't confuse this with the actual gram or ounce weight listed on the label, which reflects the heaviness of the yarn. I am referring to weight as it is called for in a pattern, such as sock-weight, worsted-weight or bulky-weight, to name a few. It can be a mind boggling affair and it is not uncommon for experienced knitters to disagree about the weight of any particular yarn they are considering.
