concrete wall stones?

Question: Can anyone tell me how you create the "rough look" on the face of wedge stones for making a wall? I want to make a wooden mold large enough to make maybe a dozen at a time. I am aware that you can purchase rubber molds for making paving stones but have been unable to find one for making wedge stones.

Answer: Make your own rubber molds from silicone rubber, find or make from plaster, a rough surface that appeals to you. Coat lightly with Vaseline and butter it up with a quarter inch of silicone rubber from the hardware store, embed a layer of dryer sheets or cheese cloth in it to reinforce it and build it up to the desired thickness a layer at a time allowing each layer to cure, make the final coating an inch or two of plaster of paris to maintain the shape ( the plaster jacket) when this is complete place the mold in position in your block mold and pour a plaster "backing" to support it while you cast the concrete wedges... the process is fun and messy, wear rubber gloves under your work gloves as has silicone has to wear off skin. The library has books on making molds usually in "stage craft" or model making" just scale it up, good luck!
