Sadly I ran out of yarn half way through. I've had the yarn so long I couldn't remember what the ply was, so the hat is also too small. Hat fail.
I was showing the failure of a hat to my sister, when she pointed out that the demi-hat was about the same size as a small teapot. Just like the one I've been putting a big tea-cozy on to keep warm, whenever she visits.
After a quick unravel and a few pattern adjustments, (and a little bit of swearing,) I had a new tea-cozy.
I even had enough yarn left over to make a pom pom. Tea-cozy win.
