Sized for the whole family (child, small adult, and larger adult), you'll need either one, one, or two skeins of yarn for a single beanie. It's designed to be made by advanced beginners to the marvelous art of crochet, who will need a 3.25 mm (size D) hook. You'll need to know how to do a single and double crochet, an increase, a slip stitch, a space, and a chain. (See? It really isn't that hard, and the results are so cute!) This is a really speedy project to do; it's great for a last-minute present or a take-along while traveling.
