Just use whatever is around: your head, your girlfriend's ass, the cat... they all work.
The more ridged or complex the surface, the better an optical mouse tracks.
As well, more opaque surfaces provide better tracking for optical lasers than transparent, as well as matte surfaces being better than somewhat reflective surfaces.
Plus the surface of mousepads may provide more or less friction/resistance, depending on what suits your style.
It makes a big difference if you're into games.
