/diy/ - Do It Yourself

I must be retarded. I cannot find a good guide on how to make a wall like picrel without the wood part. Specifically, a 2foot cobblestone retaining wall, utilizing mortar or cement. It won't be very load-bearing, 80% decoration 20% to create a clean terraced area.
I've looked up fieldstone, cobblestone, riverstone, and they all do psuedo-walls with fake thin rocks mortared onto wood.
Any advice, or should I just go with brick/timber/combination? Good stones are too expensive for me
