I was reading an article about how to lose 500 calories a day. Even though I don't knit (my hands just won't let me), I found this little blurb especially interesting.
Get out your knitting needles. An afternoon of knitting can burn more than 500 calories (at a rate of about 100 an hour).
Just thought I'd brighten your day!
So next time your S.O. gives you "that look" when you're busy knitting, tell them you're 'exercising'.
