The Boring Bloke Beanie to the rescue!
It's a crochet pattern for a classic beanie made with DK-weight yarn. (Lighter weight and thus perfect for stuffing into a coat pocket and taking it out when needed.)
I got the idea for the pattern name when I read an article on the annual Beanie Festival in Alice Springs, Australia, where you can buy everything from elaborate sculptural hat masterpieces to a "boring bloke's beanie."
Even if you're not a bloke, sometimes a minimalist hat is the perfect choice.
Just released, the pattern is now available in my Ravelry store here, and in my Etsy shop here.
