Clear the area of grass, sod, weeds and debris with gardening tools, such as rakes and shovels. Level the soil so that there are no mounds or hills and fill up any holes with more soil. Treat the soil with a pre-emergent herbicide to prevent the growth of weeds.
Unroll the geotextile fabric over the soil, starting at from one end of the lawn area and working your way across. Cut the fabric with scissors when you get to the other end. If the work area is wider than the geotextile fabric then lay strips of the fabric until it is covered. Let the strips overlap by at least 3 inches. Secure the overlapping areas with anchor pins.
Spread several inches of the stone on the geotextile fabric. Ensure that the stone is at uniform depth all over the area. According to Cornell University Extension, uneven spots are susceptible to weeds and leave the soil unprotected.
