I had someone order this cake from me for an 80th birthday on 4th of July. It's a 12x18" vanilla cake. I used the airbrush to spray blue on the sides of the cake (I used the garland marker in order to get the curved shapes) and used tip#18 zig zags around the half circles. I used tip#7for the bottom boarder and tip#21 for the top border. I used the stars fondant cutters to make the star outlines and outlined them with tip#3 and filled in with tip#18.
