Check out all my project notes including all my modifications and how I managed the problem of my hat top looking like a sphincter at www.GetYourKnitTogether.com!

Extremely easy pattern with great final product.
Cast on 45 (I have a huge head so I added some extra stitches).

Did a simple crochet edge to finish it up instead of the ribbed brim. Rather than a pompom. I crocheted the top hole closed into a tiny circle. Love this hat! Made matching mittens.
