The book The Mitten is by Jan Brett. She has lots of wonderful children's books out, and she is best known for her intricate illustrations. If they like The Mitten, try The Hat. She has a website, too. Her books have been around for a long time, so they should be very easy to find. I've been working on my knitting and purling tonight--very uneven. Oh well. Kindergartners are very forgiving. :D
No, I am not ashamed that I have a major crush on a man who dressed in tights and made faces for most of the 80's, and now plays a crippled drug addicted doctor...and is almost the same age as my father.
