making a domino x 23

I am going to construct 23 identical 3-d boxes from black card. I know that this will be very tedious but I'm going to make sure they are all exactly the same size.

22 boxes and many hours later...

I added the detail to each domino in cut-up white paper, using a holepuncher to create the white dots.

Now that this part is over I can start working on how to layout my poster by experimenting with different ways of photographing the dominos.
