    thanks to all.

    I ordered the paper from Amazon.
    My plan is to pre-finish with two coats of shellac so I get sort of a natural look but a more pleasing feel.

    If you finish the wood before you engrave you just need to wipe the residue off with a damp cloth . I never mask finished wood waste of time and money

    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.

    Besides less effort, I think a wood ornament with a nice subtle bit of finish will look better than raw plywood, but that is just my opinion.

    Release paper doesn't always adhere really well to plywood. Get something with a good strong tack and really roll it well to get it to adhere. Start lasering as soon as you are done applying the release paper to minimize the chance of the paper not sticking for long.

    With a finish, it depends on the finish, and how you engrave it. It's not that hard to melt or burn the finish at the edges if you're going deep. My BIL lasers 20-50 cedar boxes every day, and every one gets transfer taped-- for 2 reasons- first he does a 50dpi quick low power run to 'brown' the tape to make sure scrolls & stuff are visually aligned, then he does one slow deep pass. When done he wets the paper with a damp rag, pulls off the outside piece, and uses a 'rowmark squeegee' and some compressed air to remove the small pieces, takes only seconds.

    Another neat trick for some wood items, like Xmas ornaments, fight fire with fire-- take a propane torch to it when done and add to the burn
