Why would you need a tutorial for facesets? It's more of a "can you draw?" sort of thing. Just make a 192x192 bitmap. Each "face" is in a 42x42 square, and you go from there.. Of course, you can always grab graphics from whatever you want, and shrink it down to 42x42 instead of making one yourself.
