I would like to engrave an image on a serving tray made of acrylic, like this one (happens to be perfectly sized at 20x12):
I know that some acrylic engraves better than others, is there a way to tell which kind this is? And if I could do it in proofgrade, how would I go about attaching the side pieces so that it is sturdy? Proofgrade ends up being cheaper than the one in the link, but not if I mess up three sheets trying to get some kind of assembly to work. Also not sure what to do with the corners if I tried to glue something together. So I am wondering if just buying something like this and engraving it might be better in the long run.
