Love it. I don't want to give it away too much, but if you loved I Want My Hat Back, you'll recognize Jon Klassen's illustration style (also check out his concept drawings for the Coraline movie at http://www.burstofbeaden.com/). The story is by Mac Barnett, another rising star. This is an awesome use of color and would make a great addition to a storytime about winter, yarn/string, or clothing.
