Last fall, I finished the first of two different types of retaining walls that I have been working on for the Hot Springs Junction module. That post can be viewed HERE. Now it's time to finish the second type of retaining wall which is a more simple design but there is a lot of it. For the background on both types of walls see the post Japanese Style Retaining Walls.
When doing the front facing surface I set a thin sheet of scrap over the tile surface to protect it from being scratched by the saw.
The next step before installing the wall is to give it some basic weathering. I like to highlight the grooves between the tiles by using diluted India Ink.
