Two-colour Brioche Hat (Ravelry project link). I learned how to do two-colour brioche, which was a little odd to start with but cruised along smoothly once I got the hang of it. I had to get a little inventive to pick up and add a brim when it proved too short, but that was good mental exercise!
Son loved it, so I’m calling it a win.

looks good Kate, hope Jeremy doesn’t intend to go ignite too often.
Thanks Neri – thankfully he usually wears the brim up when actually walking around, so far no injuries due to colliding with anything while going incognito 🙂
