Question: how much is 1 skein?
Answer: In the US yarn is sold by weight, so this skein is 7 ounces or 198 grams. The yardage given is an estimate and is the least amount of yarn you will encounter in the skein; the actual amount may be more. Since yarn is sold by weight and not by yardage no two skeins of yarn will have the exact same yardage.
