Once the trench was dug, we bought this paver sand. This material is used to provide a solid base for retaining walls and patios. If we had put the pavers directly on the dirt in the trench, it would eventually have settled and been uneven. The paver sand locks the blocks in place and prevents settling.
Hopscotch made with pavers in garden or backyard. Made by purchasing 12"x12"x2" smooth gray stepping stone. Simply paint with a product such as Patio Paint, intended for terra cotta pots that stay outdoors in whatever colors you want. Be sure to dig 3 inches down to allow for paver sand so stones will lay smoothly.
