I suggest buying a piece of Melamine, and then drawing on it with permanent marker. It is white, and takes marker ink very well, although you will have to touch it up occasionally, depending how much you play. As for the pictures, you could either get some real good clear tape, like from 3M, or you can try put a couple coats of poly over the whole board, but I don’t know how well it witt adhere to the Melamine.

Do what I do when I make/paint things, use trail & error. Try out your paints etc.on a waste piece of ply, much more fun to do it all yourself.

paint it flat green and put a coat of polyurethane on it for two reasons, one it will not absorb any spilt beer and two it’s easy to clean. What you need is a solution to the balls that fly around the floor and pick up fur balls and then on the next toss end up in the beer you must drink, …yummmmm
