Icelandic wool hat....

....per my son's request.
It's getting there. What's getting there? Me getting the sweater knit that my son saw and asked me to knit up for him.
I charted the design and decided to knit a hat, for practice. So far, so good. I think he's going to like it.
I used Reynold's Lopi from Halcyon, US sz 10 1/2 needles to get 3.25 stitches to 1". I've been wondering whether to use a lighter yarn for the medium brown.......to help the dark brown stand out more.
