When we went on a cruise a few years ago, we went snorkeling. We took two underwater cameras. When we were done we had 50 pictures of FISH.
So what I did is a top boarder in blue with waves that was about 1 to 1 1/2 inches thick and had wavy lines of the lyrics of Under the Sea written on it. Then I took all of the fish pictures, or at least the ones that came out and cropped all of them into different size circles - kind of bubbly looking. Then put them all over the page in no particular order. Some of them I overlapped on each other. I then added stickers of fish and jelly fish and crabs.
