I put a band of about 6-8 rows of stockinette after the garter brim section. I kept using the small needle. I wanted to see what this yarn looked like in stockinette. It turns out that this is a nice addition to the hat! It creates some definition between brim and hat that I really like.

Also, since the smaller needles had too long a cable to use in the round but not quite long enough for magic loop, I started the hat flat and then joined after the brim. I think I am going to attach the two edges using a button and create a fake button closure. You can see on the right of the top picture that it is currently closed with a cable needle! When I get home I will select and attach a button from my collection.
