This chunky crochet hat pattern is given in one size to fit an adult small. But, you can easily increase or decrease this to any size you need to from baby to adult.
I used a bulky yarn, which helps it to work up super quick!
The stitch pattern is the clustered v-stitch. It's a bit of an open stitch, making the hat perfect for transitional weather. Or, wear it underneath a winter hood for extra warmth.
