This is precisely why I started my love your library challenge this year. I was watching my books and magazines pile up, and I just knew I wasn't knitting enough from them. But I didn't actually sit down and do the math like this. And it's ... a little startling, to say the least.
Looks like I'll be focusing my energy on knitting out of my magazines for the rest of this year!
P.S. For those of you who like the idea of the love your library challenge, feel free to join in! It's okay to start mid-year. Come back at the end of April to add a link to your monthly wrap-up/next month's goals blog post.
