One size, adult
Finished size approx. 21” circumference, when using recommended needle sizes and yarn weight.

I didn’t figure out my gage. I was having too much fun creating the chart and knitting some hats.

Sizing can be influenced by changing yarn weight and needle size.

Due to requests, I’m working on a child size version.
