Step 4: Hands off...
I used the cuff cut off of a white sock.
Turn it inside out and seam the the cut side in a semicircle.
Turn it back out. Use a sewing machine to put in 3 divisions for the fingers. (Most cartoon characters only have four digits)
Stuff with a bit of fiberfill.
Use a magic marker to draw on details.
Sew to the black sock portion.
Stuff that with fiberfill or a small chunk of the foam pipe insulation.
Sew the end to the middle seam of the sock tube.
