Slice the watermelon into 1 inch round slices, and then cut out star shapes using a three-inch star-shaped cookie cutter.
Gently slide the blueberries on wooden skewers and finally place a watermelon star on the top. Or add blueberries and watermelon stars in whatever order you prefer!
Place the skewers in a tall glass or in decorated floral foam as an edible centerpiece.
