Have you checked the pattern books at JoAnn Fabrics? Most of them have a crafts section, and that is where you find the stuffed animal patterns.
You may also be able to find a pattern by looking at the pattern books online. Simplicity, McCall's and Vogue are the companies that come to mind.
Also check your library for books on making teddy bears. These often have patterns in them.
Here is a link to a bear-making book at Amazon (be sure to read the reviews):
