We will discuss the characteristics of yarn, including weights, the numbering system for yarn weights, how to determine the weight of your yarn in case you’ve lost the label, and tips for determining the fiber content. We will also learn how to determine the amount of yarn needed for a project if you are using a different yarn than specified in the pattern, and how to estimate yarn amounts for a pattern you are creating. Bring some scrap yarn and appropriate size needles for knitting a swatch.
