For 2.75D Dungeon Terrain, this is great stuff. It is a matter of print, build, repeat. I prefer to print on full sheet label paper, cut, peel, and mount onto 2mm thick, cardboard backing board, from a local framing shop. Cut those to size, using either a gray, or a black, marker to 'paint' the edges with. A quick application of translucent (non-shiny) Scotch Tape wrapping around the length of the edges helps prevent peeling, over time.

I use a table saw to cut a 1/4" deep, 1" grid into 1" thick foam floor mats, from my local Harbor Freight store. I use 3-4 colors of craft paints (white, tan, medium brown, dark yellow), applying them with a natural sponge, and wet blending them, on the mats, to create a mottled dungeon floor surface. I slot the finished cards into the rubber mats (after they completely dry, of course), to build out my dungeon of rooms, chambers, and hallways. Here is a link to an image.

I plan to use this approach to build out the dungeons of G3: Halls of the Fire Giant King, for a full immersion gaming experience, complete with all the miniatures needed. This set makes that possible! Cheers!
