This is a better representation of the actual color of the yarn. I knit the ribbed band to 5.5 inches, for a longer fold-over brim. This took only one ball of the Chiara.
It's a bit snug. I did the entire hat on US 5 needles. It's a clear, well-written pattern with some clever decreases at the crown. I'm temped to cast on for another, while the pattern is fresh in my mind. I would move up a needle size, cast on 112 (rather than casting on 102 for the ribbing and then increasing 10 for the body) and do k2p2 ribbing for the brim. I might just have to go digging into my stash for alpaca yarn.
