I then watercolored the background gray and the elephants themselves in a rainbow of colors, from yellow to orange, red, pink, purple, and finally blue. It turns out that Memento ink is water resistant after it dries, and worked better than I expected with watercoloring.
Since the watercoloring partially obscured the stamped images after they dried, I went back over all the elephants with a black Sharpie pen. I cut the watercolored panel diagonally to split it apart, and stamped the birthday sentiment in between, along with adding some rhinestones and paper piercing.
