Arkham Horror: The Card Game is one of my favorite activities with my partner and friends. One of the many tokens it features is called resource and is represented by a wooden crate, which we thought would be fun to turn into a 3D thing. Zac painted tiny cubes with different shades of brown and sanded them for a cool effect. I then drew in details with a fine black pen!
Another thing that I love doing is doodling on our campaign logs. :)
