To simple it down, you could make it a single layer with just stamped squares or circles. If you wanted to make it a bit fancier, you could have different types of embellishments in each spot. You could also make it into a pieced together mosaic, where you stamp on one larger square, then cut it up. It's up to you! Each of my squares measures 1-1/4, with a 1-3/8 mat.
