Summarize:

Your foam ball or ball halves will be the eyes of your puppet. If you just have a foam ball, then you will need to cut it in half. Then, take the two halves of the foam ball and lay them flat side down. Next, use the precision knife to cut off a piece of the foam near the edge. When you are finished, you should have two foam ball halves that have a flat edge on one side. You should be able to place the foam pieces side-by-side and they should fit together. Cut out two thin strips of black craft foam. Then, use hot glue to attach these strips to the rounded parts of the foam so that they look like the edges of eyelids. Next, cut off a piece of your second fuzzy sock. The piece should be wide enough and long enough to wrap all the way around the foam ball. Glue the sock material over the eyelid area to create the fuzzy eyelids. Cut off any excess sock material from the edges of the eyelids. Cut out two 1.5 centimeter circles from the black craft foam. Then, cut out a small wedge from each of the circles. Next, glue the circles onto the rounded foam part of the eyes so that the wedges are pointing in the same direction (either to the right or to the left). Once your eyes are finished, you can glue them to your sock. Glue the eyes onto the fuzzy side of the sock, opposite the puppet's mouth. The flat sides of the eye pieces should be facing each other. The eyes should also be placed close together so that the fuzzy sock borders are touching.
Shape the foam for the eyes. Make the eyelids. Add the pupils. Attach the eyes.
