Thirteen hats there, & the 14th on my hook will finally catch me up. I'm trying to be creative & so far no repeats. But the chances of coming up with 40 different, workable, variations...I don't know about that.
I aspire to one day be as witty as some of the folks I read. Though I've been told I'm hilarious in person, most of my humor relies on tone and inflection, and thus falls flat in the written word. But I'm good at being maudlin in print. Really.
Oh, and I like crocheting. A lot. And I'll gouge your eyes out with a 3.75mm hook if you suggest it's a) less versatile than knitting or b) the same thing as knitting.
