I can't think of a better way to keep your head toasty than with a knit hat that references video games and other geeky material in an 8-Bit form.
These beautiful, hand made hats were made by billionsandbillions, and you can head over to their Etsy page to purchase one of these creations.
Sure, they are a little expensive but you have to remember that someone made this for YOU! Plus, you will probably be one of the few people in your social circle to own one. You'll be the talk of the town and you'll make everyone green with envy.
