The Parker Crochet Head Warmer
More than just a headband or ear warmer, the Crochet Head Warmer is a gorgeous and unique winter accessory. It's the perfect handmade blend of a headband and earmuffs that will keep you warm through the cold winter months. I love the idea of giving a regular ear warmer headband extra warmth by adding on ear flaps. They are like ear muffs, but better in my opinion. This pattern is not as complicated as it looks!
