This was the very first colorwork pattern I scribbled on notebook paper many years ago. I’ve made dozens of versions of the hat through the years, but am just finally writing the pattern in file form. I’ve named the hat after a local rock formation right off shore in Lake Superior, Hollow Rock. There is a beautiful gap in the bottom of this small rocky island, and photographers love to go before sun-up and line the sunrise up with the gap- creating the most beautiful scene of diamond shaped sun rays poking through. The pattern is written in 4 sizes, child, youth/adult small, adult m/l, and adult xl.
