We used different colors of tape and markers to decorate our spaceship. (You could decorate your ship with any embellishments you'd like.) We used red duct tape for the rockets, outlined with the marker. (We used a permanent marker since washable markers don't work well on duct tape, but you could certainly use washable markers to decorate the carton). At that point, my son declared his spaceship "awesome," loaded it up with cars, and zoomed away!
