Because stepping stones cover less ground than a sidewalk, they are an environmentally friendly way to create a path through a garden. Rainwater can be absorbed by the ground between and surrounding stepping stones, which reduces runoff. Stepping stones also help to keep foot traffic off your turf, preserving your lawn or garden. They can also be set flush into the ground so they are simple to mow over. You can even create your own garden path stones at home.
Bend the heating duct galvanized steel strip into the desired shape for your stepping stone. The strip can be made into a circle, square or other shape. Overlap the ends and secure with duct tape.
Coat the inside of the strip with cooking oil to help release the stone when it is dry.
Cut a piece of chicken wire using wire cutters so that it is slightly smaller than the stepping stone mold. Set aside.
Place a piece of plastic wrap onto a plywood board. Cover with the stepping stone mold.
Mix 1 part concrete mix with water in a bucket until the mix is the consistency of a mud pie. Press the mixture into the stepping stone mold until the mold is halfway full. Pack firmly to dislodge all air bubbles.
Place the chicken wire on top of the cement. The chicken wire will reinforce the stone and prevent cracking and breaking as people step on it.
Fill the mold the rest of the way with concrete mix. Mist the concrete mix with a misting bottle filled with water and cover with plastic.
Wait 24 hours for the concrete to set. Remove the galvanized strip from around the edge of the stepping stone. Scrape the edges of the concrete with a knife or a wire-bristled brush to soften the hard edges of the stepping stone and remove concrete scale. Re-wrap the stepping stone in plastic.
Leave the concrete to cure. Remove the plastic every 24 hours to mist with water and re-cover. Concrete cures at different rates depending on the temperature. Generally the stone will be cured after one week.
