After spreading frosting over the top and sides of the sheet cake, mark a rectangle in the upper left-hand corner of the cake for the "blue rectangle" and then mark 3 horizontal lines for the white "stripes" across the cake.
Tip: You can use a ruler to help you mark straight lines with equal spacing in between or just do it freehand. Two of the lines will run across the whole cake, the third line should start in the middle of the right-hand side of the marked rectangle.
Gently pat raspberries dry with a paper towel to dry. Make 3 "stripes" of raspberries on the marked horizontal lines.
Tip: Take a little extra time to make sure your berries are as dry as possible; wet berries will make the dusting of the confectioner’s sugar (to finish the cake) melt.
Gently pat blueberries with a paper towel to dry. Place half of the blueberries in the "blue rectangle," leaving a space between each berry.
Tip: The space between each berry should be about the size of a blueberry. If you place all the berries with the stem end pointing up, they will look the best.
Sift 2 tablespoons confectioners’ sugar over the raspberries and blueberries to make them the white "stripes" and "stars."
Tip: Use a flour sifter or a fine-mesh sieve to help you make a fine dusting of confectioner’s sugar over all the berries. The coating of sugar will seem generous, but you want enough to make the berries look like they are well coated with white.
Fill the rest of the "blue rectangle" with the remaining blueberries.
Tip: If it seems tricky to fit the blueberries into the spaces in between the dusted blueberries, try using a pair of clean tweezers to help you nestle the berries into place. It take a little extra time, but may be a little easier than using your fingers.
Place strawberries between the rows of raspberries as the red "stripes."
Tip: For the prettiest rows of strawberries, slice the berries lengthwise rather than crosswise so they look almost like triangles, then place them on the sheet cake alternating which direction the tip is pointing so they fit together like puzzle pieces.
