To make this, I started out with a piece of 16x20 Canson Art Board. My hubby helped out by making the lines with a pencil for the grids while I was cutting the images out. I selected my paint that matched the papers I was using, they are Pool Blue, Bright Yellow and Valentine Pink.
For the clone troopers, I used an SVG cut file and cut them out using the Cricut Expression cutting machine. Once I cut the bases out, I layed them down on the grids to determine what color needed to be painted in each background and used a pencil to mark each squar.
To finish this, I painted the board. (I erased the pencil lines as I was filling in each square) Then, I put my clone troopers together and attached them to the art board using an adtech tape runner.
