I'm going to try to make a concrete checker board and pieces

I'm on the job. I'm posting in advance so I don't chicken out. :-)
Because this is my first attempt at this type of board I'm going experimental all the way.
I just mixed up a bunch of new recipes and colors and I'm making the squares and the checkers this afternoon if I have time. Then if they are hard enough tomorrow I will form the base.
I'll take a few pictures of how I approach this and post them good bad or ugly. :-)
I'm going to use hardware cloth, in the base but given the size I expect this board to be a bit fragile.
