This hat was inspired by the hat that Emily Deschanel wore in the Bones episode, The Blackout in the Blizzard. It is a slouchy tam with a pom pom, and fully finished crown decreases (to allow knitters to omit the pom pom if it’s not their thing).
Very Hungry Caterpillar - Adorable baby gift or costume! This doesn't link to a pattern but is easy to accomplish by changing up the colors on an existing pattern, then adding the simple details to the hat. Would work for knit or crochet.
