Make a mold out of a flat container that is at least 4 feet long and 2 feet wide. Fill the container with 3 inches of sand.
Place a drop cloth between the leaf and sand for a clean, smooth look. Using only sand will provide more texture and a rustic look.
Press the leaf 1½ to 2 inches into the sand with the vein side of the leaf facing up. Press the leaf flat into the sand to prevent a cup-shaped stepping stone. Mist the sand with water and pack it in place. The leaf pattern will show more definition when the sand is dampened. Do not remove the leaf.
Prepare the quick-drying cement in a bucket and make enough for the number of stones you will be creating. Pour the cement in the leaf indentation, making it even with the sand layer. Cement that is spilled outside the mold should be wiped immediately before it dries. Let the stone dry completely before removing it. Quick-dry cement will dry in approximately 20 minutes, however, it is best to leave the stone for at least an hour to let it harden.
Remove the stone from the sand mold and clean off any leaf or sand residue. The side the leaf was pulled off is the top of the stone. You can use the stone as is or apply paint or glaze if desired.
