Clean the peanut jar; you can also use any other jar. Round shaped jars make cute snowmen. Wash and dry the jar and fill it with the cotton balls. This is to create the snow effect. You can also paint the jar white but cotton balls give a more realistic look.
Attach the two googly eyes to the jar as eyes of the snowman. You can also simply use two black buttons for the same purpose. Cut out a small triangle from the craft foam to make do as the nose. Stick it under the eyes at the appropriate location.
Now use the black craft paper to cut out the mouth of your snowman. A creative way is to cut out small equal circles and stick them to the jar in a wide smile pattern.
Cut a long and thin piece of felt that is enough to be wrapped around the jar. This will act as the scarf of the snowman. To give a more realistic touch, you can use a real fabric instead of the felt. Now fit the sock over the jar to work as the hat. You can also get a characteristic snowman hat from a craft store.
