On a snowy day, Sarah notices that a little boy at the bus stop does not have any mittens. Worried that he couldn't join in the winter fun, Sarah knits mittens for the little boy, placing them on a tree at the bus stop the next day. Each day thereafter, the children look for new mittens, and every day Sarah knits new ones. One morning she covers every branch with bright new mittens for the children. Though she has used up all her yarn, Sarah returns home with a full heart and discovers a wonderful surprise waiting on her porch. Full color.
