Hilary's Girly Girl Hat Free Crochet Pattern

OK, that's not Hilary, that's me, Hilary is much younger and prettier. I also did not make this hat for Hilary, it will be going to some as yet undetermined charity. What I did make for Hilary's mother is this pattern so she could make Hilary this hat. Hilary's mother (aka my cousin Marie) showed me a pattern for a baby hat and wanted to know how to re-size it for an adult. I told her I could do even better, I'd do the whole pattern. She also mentioned that Hilary was a girly girl, hence the name of the hat. So now I'll share the pattern with everyone for free:

You will need 4 ounces of worsted weight yarn and an I hook. If I seem to be using an I hook all the time it's because it's one of the few I can find. Someone told me to blame my cats and they're probably right.
