So watermelons, seriously? Yes. Watermelon red to be exact or watermelon pink if you'd like. Whatever the case think reds or pinks with greens and black. You can add polka dots or go for a very casual approach and use the red and white picnic table checks pattern. In my head though I can see this done fancy-like just by toning down the watermelon motif. Whatever you do a watermelon theme is fresh and sweet. Perfect for summer time quinces!
