I'm contemplating creating a textured table surface for playing Runewars. I'd like to do grass and sand. My question is, does this game play okay on flocking? How about sand? My concern is that the trays will drag and scrape off the texturing. Anybody have any experience with this?

We never tried it. Closest we ever got was an old army surplus blanket of some sort. Had a nice green texture to it that looks a lot like grass for our purposes
