A few weeks ago Sean Sutter (creator of Relicblade and Sludge) posted on Instagram that he had made a 2x2 gaming table using a wooden artist panel and some knockdown wall spray. It seemed pretty simple and turned out really well so I gave it a try myself. 2x2 is the right size to play Forbidden Psalm, Rangers of Shadow Deep, and Lobster Pot, and some other games that I'm interested in.

Including drying time this only took about 6 hours to do and I think it came out really well. There's a spot in the middle of the board where my first spray came out too thin but otherwise it worked about as well as I could have hoped.
