Hats are one of the most-loved first projects: they work up fast, use a single skein, and let you practice working in the round. Every hat pattern below includes the target finished circumference and a sizing guide so you can match an adult, child, or baby head.
For a snug fit, aim for about 1 inch of negative ease — that is, the finished hat circumference should be about 1 inch smaller than the wearer's head. Crochet stretches; a too-loose hat tends to fall over the eyes.
