Leaf Castings

Step 4 Mixture

Mix the concrete and water a little at a time until you get a brownie batter-like consistency. You do not want the mixture to be too soupy as the slurry can get under the leaf and make for an unattractive leaf casting. If the mixture is too dry,you won't see the vein details of the leaf. You want the mixture to sit on the mound of sand and not slide off.
