Lay Handy-Edge units in your desired pattern. You can work in short sections to help ensure the desired outcome.
Dig a shallow trench approximately 3 to 3-1/2 inches deep. The units will sit in this trench.
To aid in leveling, add a small amount of sand to the trench and spread evenly using a trowel.
Place Handy-Edge units in the trench. Use a rubber mallet to seat units in the sand. To level many units as once, lay a piece of wood across several units and hit with a mallet.
