Family member's son was getting married locally on the beach. His bride-to-be gave me the wedding colors (the tan and blue seen in the pic) and said she like seashells and square cakes, so this was the design that I created for them. Luckily, it was a hit! The shells are all white chocolate, the sand is crushed graham crackers, and the cake is fondant-covered with fondant "waves" (blue) and "sand dunes" (tan).
