Nature makes wonderful patterns that easily transfer to concrete. We used a hosta leaf, but any large leaf will do. Use the underside of the leaf because the veining is more pronounced and will be more dramatic on your stone. Always keep concrete inside the outline of the leaf; any concrete that goes over the edge will stick and harden to the cardboard.
Time: 2 hours

Easy Release: Before filling the mold, spray it with cooking spray. And before turning the mold over after the concrete has dried, pull the edges of the mold away from the concrete. Tapping the bottom of the mold may also help.
Curing: After the concrete has dried, you can remove it from the mold, but it's not ready for finishing: It still has to cure. That process takes several days to a week, depending on the type of concrete and weather conditions. Be sure to follow the manufacturer's instructions to get the best results.
