Starting with blue icing, begin piping ice pops around sides of cake (4 rows of 5 stars). Continue with white icing (4 rows of 5 stars). Finish pops with red icing, tapering to a point (one row of 5 stars, then 4, then 3, 2 and then 1).
Prepare decorating bag with tip 47 and brown icing. With smooth side of tip facing up, pipe sticks.
