This pattern is easily adjustable for different sized heads. You can stop the increases at any time when you have reached the desired circumference with noting that adding the brim will tighten the circumference by about an inch. Omit picots for a male hat.

This pattern is similar style to the Crochet Rainbow Beannie with Picot Edging. The difference is that this pattern version has been reworked for thicker weight, cotton yarn.
