Add some extra color to your "yard card" school displays with Blue Star Yard Signs. Mix and match the star yard signs with other symbols, numbers, and letters (not included) to create one-of-a-kind outdoor messages. Displayed on any of your school's lawns, they will really have an impact parents, students, passersby, teachers, and more. Made of a sturdy, plastic corrugated material, the Blue Star Yard Signs come in 15" high x 16" wide and 20" high x 22" wide sizes; both include 15" wire stakes for easy display. The material is both water-proof and weather-resistant, so the yard signs are sturdy enough to withstand most types of weather. Use your Blue Star Yard Sign(s) for game days, patriotic holidays, Field Day, Teacher Appreciation Week, graduation, and more. NOTE: A minimal amount of assembly is required. No set-up charge!
