My best friends daughter wanted a "fruit cake" for her 5th birthday. This turned out super cute, and was very easy! First I sliced the watermelon, then placed octagons (printed off the computer and cut out) onto the slices so I knew where to cut. Using cookie cutters we made the hearts from cantaloupe and kiwi (the grapes are held on with tooth picks). We used chopsticks to hold all 4 tiers together. The thinner your hearts are, the better they stick to the watermelon. Good luck!
