I made a few sketches of what the pieces ought to look like, influenced by the look of both the original flat tiles and the commercial resin set, as well as the practicalities of making plywood shapes 3D. I then sketched out the shapes I thought would look OK on the piece of 1/4" plywood, and sketched a border, too. The border was to have indentations the right shape to accept the cardboard chits that represent ports in the game. Each tile needs a flat part on it so the number markers can sit flat (and they have to sit perfectly flat or the robber will go sliding off!), so this also constrained the design somewhat.
