Inspiration at Art Machines - Plated Hat

I like the very subtle color scheme of this hat.  The ribbed plating is just enough variation to look interesting.  In the past, when I've played with it, I thought it was funky-looking, but I was using yarns with too much contrast, i think.  Anna's is rather elegant.
