Portable Pike and Shot 'Griddled'

I added the grid squares to the recycled battlefield board this morning, using a green Sharpie marker pen and a ruler. I fluffed up one row but managed to cover it up and redo it before anyone noticed. Up close the grid is clearly visible but at arms length it blends in nicely with the grass green paintwork. I now need to make some terrain templates to place on top of the grid and get my armies painted for a try out game.
