Just for the fancy pics, as chuckknuckle says, sand on a board in normal circumstances is bloody ridiculous. I hail from the days of Rogue Trader, I have seen what a sand textured board can do to painted miniatures and it's the stuff of nightmares! Saying that is was super easy to clean up, just fold up the mat and pour it back into the jar, very Zen...unless you sneeze
however if you want that sort of look fine grain kiln dried sand sprinkled over the board is surprisingly gentle to miniatures it would just get EVERYWHERE in normal gaming circumstances it does look quite cool (in a hot way deserty way) though!
