My attempt at a gaming table. Turned out really good:
2x2ft tiles (8 of them)
Plaster put down, modeled after the GW gaming board.
This is what I used to model it after, it is a printout and I made a small tool to make the cracks in the wet plaster.
Covering the road parts so the plaster could be put down
Plaster complete, time to dry.
First coat down.
Base coat with sand.
Finished example layout. I still had two more pieces to do so that's why the road doesn't line up.
