Actually the wallpaper was fairly easy, just cropped the image to match the vinyl after application, then sized to my resolution.
The keyboard was a print/lam/contourcut, then I applied each piece separately. No trimming needed on those, though it took a while to measure them and lay out the design.
It's been holding up well so far, although I don't type a lot. I did have 2 small trouble spots where the vinyl was stretched and it pulled back a little. I should have tried using primer 94.
