To make the card you may want to use a stamp positioning tool, such as MISTI. Cut two pieces of 3 3/4″ x 5″ card stock and stamp the two fish at the same spots on each of then. Die cut the fish out from one of the panels. On the panel where you die cut the fish stamp the sentiment and the bubbles.
You can save the die cut fish for another project. Color the fish on the panel that wasn’t die cut. Adhere the two panels together using foam mounting tape so the one with the sentiment is on top. Adhere to pool colored note card.
