    Along those lines, the new "print and cut" feature is pretty amazing for alignment and doesn't even require a camera. Check it out if you haven't tried it yet.

    I agree with Bert that there shouldn't be a need to put down the release paper if you put on a finish first. Most likely that would be a waste of your time.
