For my SE mod, I printed the art without the hole layers, put it on the faceplate, and then trimmed the holes with an exacto. I used lami-label from Kinkos, so the art was stuck very firmly in place while I cut the holes out from the reverse side. (I put a the faceplate upside-down on a piece of wax paper while I did this so as not to damage or scratch the art.)
I’d print the art at a pro shop, just to be sure you get the best quality. Also, make sure they have the right dimensions on their screen before the print. Mine came out a touch smaller than I’d thought it would, but it didn’t matter b/c the pic was still larger than the stick and I didn’t have any hole outlines on it.
Hope that helps–be sure to come back here with pics of the finished product.
