School Library Journal gives Extra Yarn its second starred review

From School Library Journal:

*EXTRA YARN
by Mac Barnett, illus. Jon Klassen

In a snow- and soot-covered town, Annabelle discovers a small black box filled with colorful yarn. She knits a sweater for herself, but there’s still yarn left over. From the seemingly inexhaustible supply, she knits sweaters for her dog, a boy and his dog, her classmates, her mean teacher, her parents, and people in town. In an astounding feat of urban knitting, she covers the buildings in sweatery goodness, but the yarn does not run out. Disaster strikes when a mustachioed, piratical archduke arrives, demanding that the child sell him the magic box. When she declines, he steals it but does not benefit from his crime, as he finds it empty. In a fit of rage, the archduke curses Annabelle and flings the box into the sea. Happily, it finds its way back to her full of yarn again. Klassen’s deadpan, stylized illustrations impeccably complement Barnett’s quirky droll writing. Small details like a dog’s sneer or sweater-covered mailboxes add to the subtle humor. The cheerful colors of the yarn contrast with the somber grays and blacks of the  town. Give this one to fans of offbeat stories like Florence Heide’s Princess Hyacinth: (The Surprising Story of a Girl Who Floated) (Random, 2009) or to young knitting enthusiasts.–Yelena Alekseyeva-Popova, Chappaqua Library, NY
