"This understated picture book is certain to spark the imagination of every child who comes upon it, and what could be better than that? Annabelle lives in a black and white world, where everything is drab, drab, drab. So imagine her surprise when she finds a box filled with yarn of every color. Armed with the yarn and knitting needles, she makes herself a sweater, but after she finishes, she finds that she has extra yarn left over. After knitting a sweater for her dog, her classmates, and various (hilariously unsurprised) bunnies and bears, she still has extra yarn. So, Annabelle turns her attention to things that don't usually wear wool cozies: houses and cars and mailboxes. Soon an evil archduke with a sinister mustache 'who was very fond of clothes' hears about the magic box of never-ending yarn, and he wants it for his own. Reading like a droll fairy tale, this Barnett-Klassen collaboration is both seamless and magical. The spare, elegant text and art are also infused with plenty of deadpan humor. Klassen uses ink, gouache, and digital illustration to fashion Annabelle's world.... Quirky and wonderful, this story quietly celebrates a child's ingenuity and her ability to change the world around her."—Booklist (starred review)
