Vanguard Table Delimiter

Playing on a 6'x4' mat a game that require a smaller board size? For example, the excellent Kings of War: Vanguard, that requires a 3x3 gaming area?

Then these super simple table delimiters are for you: 2" wide, 12" long, you can assemble them as you want to delimit a gaming area of your liking.

I made some of these with 3mm MDF, but I suppose you can use pretty much anything you like!
