ISO: Perfect Scarfy Gift

So my future SIL (in all of our dreams, BIL will finally decide to settle down with wonderful, amazing, best thing that ever happened to him, girlfriend) alluded to the fact that she'd love a knitted scarf for Christmas.

She's a mid-late twenties, indie/emo type of girl, who bartends and goes out a lot. Favorite color is turquoise. I'm thinking, she needs either something "cool" or something "bulky/soft", but definitely not something twee. Any ideas?

I like Diana's Steam pattern and I think it would be great in some soft Alpaca or wooly goodness.

However, I am *very* open to suggestions... help?
