Editor’s note: When I see these five posts collected in one place, my first thought is: Jillian Moreno is such a know it all.

Such a smart, sass-filled writer—how lucky we are to have her on MDK.

Each of these five pieces taught me something that I didn’t know about the nature and quality of yarn—I didn’t even know what I didn’t know!

I suggest you hunker down with a piece of knitting that involves a yarn you really like, and take a little time to read each of these posts. You’ll discover something about that yarn in your hands that you didn’t know. And you’ll carry that knowledge with you the next time you’re thinking about what yarn to use for your next project.

Thanks, Jillian!
