People usually end up taking up significant amounts of space as they build up their inventory of terrain pieces for different games and settings (for me: 25/28mm fantasy and 15mm WWII). That is unless you find a few tricks for efficient storage! I decided to make use of my basement ceiling joists. I made a few shelves by nailing a few 1″x3″ planks under joists. It works pretty good. I don’t know what I will do when I decide to finish my basement and put ceiling tiles though…
