I picked up some bamboo plywood from inventables using the credit from my glowforge purchase. But, it doesn’t come masked and when I ran a few test engraves and cuts I got smoky discoloration around the edges.
So, I went and found some suggestions to use vinyl transfer paper online. I picked up something reasonably cheap on amazon, and I have to say it worked wonders. It was very easy to apply and remove, and kept my bamboo looking perfect (except where I mis-applied the transfer paper.
Next up: I’ve got a bunch of 1/4" hardwoods and some acrylic to try it on.
