(Note on pattern: join the cast on stitches in the round)

This pattern is pretty easy. Lots of eyelets.
i’ve written instructions for two sizes, however it would be easy for someone to adjust the size for themselves. Just make sure you make the brim in multiples of six, and the body of the hat is in multiples of eight, so you’ll just have to increase a couple of stitches….unless it’s a multiple of 6 and 8…
