I bought these cute cupcake wrappers and toppers online from Etsy. They were super easy -- I just printed, cut, and used the hot glue gun to assemble. I was very pleased with how they turned out and the colors were so bright! I put oreo and graham cracker crumbs on top of the icing for a "construction" look.
These are iced sugar cookies for the party. I made construction cones, road signs, and dump trucks. I matched the icing colors with the cupcake wrappers/toppers.
Thanks to Spaceships and Laser Beams for the great birthday printables!
