Star Cookie Cutters (or any other desired shape)
Large Knife and cutting board
Simply slice the watermelon in 1 inch slices and cut out the desired star shapes. Insert the popsicle sticks in the bottom of the star. When ready to serve, place the pops in a bowl of ice so the ice acts as a stand so that the pops don't fall over. Scatter blueberries on top and around the watermelon pops. Serve and enjoy.
Note: I was able to purchase the star cookie cutters at Super Wal-Mart in a set of four assorted sizes in the bakery section. The popsicle sticks can be found at Wal-Mart in the craft section.
