Stone Edge Surfaces Southern Ledgestone decorative concrete stamp set for Stamped Concrete, Decorative Concrete, Concrete Overlay. The Southern Ledgestone stamp set is in our drystack stamp family and comes as a set of 3 large stamps. The stamps have an incredible stack stone look, but are big and may need 2 people to use them, with each stamp having two handles for application control. Each stamp is approximately 18′ x 30″ in size and are meant to be rotated 180 degrees to double the pattern, so 3 stamps can give 6 looks. For best results, always rotate the order of the 3 stamps so you do not create a predictable pattern.
