Juergen and Nicole built a wall on the weekend. It was beautiful but it did not stand because of the mortar. It just wasn't the right stuff. Juergen took the advice of the man in the store, but I guess the man didn't know what he was doing. So Nicole built another wall today with concrete mortar. And it looks like this wall will stand. So we are starting with the bottle window. This is the fun part. And here are some photo's. More photo's as we progress. It's going to be a cool green house!
