Summarize:

If you have a fabric marker that will show up on your fabric, you can use it to draw a face on your teddy bear. Draw eyes, a nose, and a mouth. Make your bear look happy, sad, grumpy, or surprised depending on what you want. For example, you could draw 2 circles with dots in the center of them and raised eyebrows for a look of surprise, a big toothy grin for a happy bear, or a straight line for a neutral expression.
Draw the eyes, nose, and mouth on the fabric for a quick and easy face.
