This is a fun hat with a band made with Bavarian Twisted stitches. If you’ve never done Bavarian knitting this simpler design would be a good place to start. As written the stitches are not twisted. To make them true Bavarian twist stitches you can knit into the back of the “k1 from cn” in the Left Twist instructions.
