This has been finished and worn for about a week now, but I've only just uploaded the photos. What can I say - time seems to run away from me...
So, this is the Jacques Cousteau hat. Notes and pattern links here. He loves it. He claims that orange is his favorite color (for now), and it looks really cool on him. Plenty of growing room (essential for a big melon), he should be able to wear this for the next couple winters. I hope.
