This brim hat pattern is given in one size, however, it can be crocheted into any size hat that you want. You can either make your increases by doing more increase rounds or simply by switching up your yarn and hook sizes… like I did.

Bumpy Ridges Hat and Cowl ~ FREE Crochet Pattern

The brown hat that you see pictured was crocheted with Loops and Threads Impeccable yarn and an I crochet hook; and the grey was done with Caron Simply Soft and an H crochet hook. The brown measures an inch wider when laying flat, but both hats are about the same height as I did more rounds on the grey hat.

Although it’s a brim hat, the acrylic gets too hot in the warmer weather. So, if crocheting this for the summer weather, you might want to use a cotton yarn instead.
