How is that for precision? From rocks that were anything but square. sometimes off by 3/4" from end to end. So 3 diamond blades and a lot of cutting went on here to get this look.

Computer Generated - I took stones and shrubs from other pictures and built this one to get an idea of what it would look like.

4 " Course - 4" Medium, 2" 1/4 inch , later to be finished off with stone dust. Drainage pipe already covered.

Held up ok.

Later I added a motor on it so that I could adjust the counter balance while sitting.

A helpful rain, helped map out what was level and how I should do the drainage.
