Have you ever wondered about all this information on the yarn ball-band that you don't understand? There is quite a lot of information on there, meant to let us as users know as much as possible about the product we are getting - How was it made? What does it contain? What kind of projects is it suitable for? How should we treat it? There is much to learn about the yarn from looking at the tag or reading the description on the website. But sometimes, even after reading it, we still don't fully understand what it means, because some of those terms are unfamiliar to us.
