Position the stones to create the track and length of the path you want. Place the stones close enough to each other so that people will be able to walk from one to another easily.
Cut around the edges of each stone with a trowel to mark the perimeter of the stone into the ground. Remove each stone and set it aside.
Dig out each stone's location down to the depth of that stone using a trowel and small shovel.
Fill in the bottoms of the holes with 1 to 2 inches of sand. This will help you level the stones, particularly on hard packed ground.
Set each stone in its respective hole. Place a level across the top of the stone. Tap it with a rubber mallet to seat it into place and adjust it for level. Continue with this process until all of the stones are in place.
