Mark the outline of the path with spray paint. It doesn't need to be two straight lines, so be creative with the design.
Dig down and remove 6 inches of the topsoil with a shovel along the entire path.
Lay 4 inches of fine crushable stone along the path and compact flat with the tamper. The more tampering you do the more stable the ground under the path will be.
Lay the stones along the path in the desired shape. If you need to remove a little of the base to get the stones to lay flat, do so with the shovel or your hand.
Pour pea stone gravel between the rocks and level them with a rake.
