The main pattern of this hat are alternating clusters and V-stitches in odd rows and chain 5 spaces on the even rows.

Instructions for clusters and V-stitches are given on the pattern.
It’s not a difficult pattern, I’d say it’s for intermediate crocheters.

I used a wagon wheel style flower as my accent and added a sparkly button in the center for some bling. You can accent it with any large flower you like. The blingy button is optional, you can use a pin instead or even omit it completely.
