More mistakes will follow, but these three hats helped to fine-tune the brief. Nothing too decorative or fanciful – do not try and anticipate a ghoulish trend. Symmetry and minimal crochet would be preferred. I wasn't asked to knit the penguin a third time, but the predictable colouring was the order of the day. Children's books and animated films should be used to define the visual language of the book. The reader shouldn't need to guess what the animal depicted is! It is hard to argue with that. Anything else seems like an indulgence. I will find this hard because I started the animal hat journey with other ideas but I have a brief to work to.
