Scarf Tying

I bought a scarf on sale this weekend at the Coach Outlet (I also bought a purse for myself, and a birthday present for Tallman... more posts to come).

I like the idea of scarves, they seem very Parisian, and practical in a chilly office (which I have).
But I'm always confused as to how to wear them.
I'm going to try wearing mine like this... its the least awful demonstration I've seen on how to wear a scarf...

Do you wear a silk scarf ever? If so... how?
