This messy bun hat is worked from the bottom up beginning with the band. You will crochet the band in rows, join it together and begin to work in rounds. This pattern includes the option step to add a contrast color stripe. The video tutorial demonstrates how to handle the color transition.

If you need to make slight adjustments to the sizing, you can only do so by changing hook sizes. The stitch pattern and decreases prevent you from easily manipulating the number of stitches. Here are my recommendations:

Child/tween – 5 mm hook
Adult small – 5.5 mm hook
Adult – 6 mm hook
Adult large – 6.5 mm hook
