have the red bricks already, 1000+, therefore I can't change brick type/style. After reading all response, I went out and digged deeper and decided to just do it, so I can't change my mind even if I want to. I used the string alignment method and lay a around 50". Looking back, my base is at last 4" deep. I feel safe now. Bricks are straight. I was happy and decided to eake a break. Stepped away from it, looked back, oh no, the line is straigth horizontally but verticlely, it is up down all over
