concrete band around it. I put alot of voids and veins in the grey band where i can go back and fill with blue concrete to match the surface. My wife saw it and is wanting to keep it for our house..... after its been sitting in my way at the shop for a year! Does anyone know where i could get some large tree stumps? i think this would look good if i made a base that was one or two large tree stumps..... or make a concrete base that looks like a tree stump with branches coming out to support it.
