I’ve seen a few maps here and there but I’ve intentionally been avoiding them because I wanted to trial and error it. I used Proofgrade Maple Veneer and some Acrylic. Found a great map site ( https://www.davidrumsey.com) and found a region that interested me. Originally was going to do multiple levels of water, but the scale at which I was working did not allow that. I think it turned out pretty good, but the smaller islands were a challenge.
