I whipped this hat up yesterday just for something different to do. The pattern said it was for newborn to 12 months (which is a pretty big range in my opinion) so imagine my surprise when it fit my nearly 18 month old perfectly! And no, she's not a tiny little thing either. My gauge was probably off...a bit, no big surprise there. I've been wanting to make her a hat anyways so isn't that convenient?! I think I'll make her a stripey one next.
