Concrete Retaining Walls

That's a great looking concrete wall!

I was at Home Depot the other day buying some lamps and ran across the bulb separators. With a little paint these may have some potential. Fancy concrete walls. Best of all the are free...

I see the potential, but then I'm one of those guys that always thought I could use those clear plastic cookie trays as roofs for passenger station platforms.  May you have more success than I!  <g>

I use a few different materials for walls. Polystyrene is easy to work with and you can make any shape you want. The wall pictured is painted with crackle spray paint. Precision Board is fun to work with because you can paint it, I used textured paint for the gray blocks, sand it and cut it just like wood only with a lot more detail. As in the brick and stone wall pictured.
