The Hat by Jan Brett is the story of a young girl, Lisa, who gets out her winter woolens and takes them to the clothesline to air out. One of her stockings blows off the line, and is investigated by the curious Hedgie. It gets stuck on his prickles, and he pretends it is a magnificent hat. The other animals are inspired by Hedgie's hat, and each becomes the owner of a new hat, in the form of Lisa's winter clothing. Lisa must chase the animals to get her clothes back, while Hedgie finally makes it back to his den.
