This is an easy pattern that can be finished in one sitting without any problems. The pattern can be done for a toddler sized head or made a little bigger to accompany a child or adult. Toddler size caps uses and size I crochet hook, while the larger size uses a size K crochet hook. The pattern is exactly the same for both. The Critter Caps are made from worsted weight yarn and can have fun fur added to create a furry effect. Instructions for adding little ear patches are also included. The hat can be lined for extra warmth or just used around the house at playtime.
