Here is my faux tiled mosaic card. You can get a great tutorial on Splitcoast showing this great technique so I am just going to direct you there to find out how!
The only thing I did differently was I used the leftover pieces from my clear stamps to make the pieces so I could keep them in a spare case and take them on and off my block so I didn't have to keep them on there forever. All you have to do is after you put your clear stamp stickers on, place the rest of the plastic cut out on the rest of the foam and line up the holes. It will fit right on and then you can just cut it up into chunks!

Here is my image before I put the Versamark on it.
And here is the front and back of what my block looked like with the rubber on it.
