There are several ways to do this. If you're confident in your tracing abilities, a fine pen and placing the shield over the nano (without wetting it) would mark its position. Then put the shield on a clean work surface and use a hobby knife to cut it out. Apply the shield as normal. Also, if you can find a full-size nano image on paper (maybe one comes with the invisible shield, as a display backing?) you could use that to cut out the circle without the use of a pen. The third method would involve measuring the diameter of the circle, and measure the distance from the edge of the iPod to the circle in all four directions. Then use a compass to make a matching circle on paper, and use it as a stencil to cut the invisible shield.
(I also don't like the idea of the whole-surface protection...the slight movement of the click wheel will produce air bubbles after a while. I think devilot76 used a screen protector that is pre-punched with a separate wheel cover. You could simply discard that piece. Search for her and find the thread where she talks about that if you want more info.)
