The Yard Card world is always evolving and changing, so we are too, by consistently adding new products to Yard Card Planet. For the latest Yard Card flair, signs and letter sets, come back often to see what's new! All graphics are professionally UV printed on one side for outdoor use on sturdy 4mm Coroplast and are weather resistant. Each yard sign is precision cut and ready to stake. Unless otherwise stated, all Yard Card Planet signs have a white border around each design. This white border is added to make the signs pop and look their very best as part of your lawn sign display.
