My wife and I had our first week out of town after 1-1/2 years hunkered down at home. One of the stops was Frank Loyd Wright's home in Wisconsin. I was familiar with a lot of his early work using darker oak, leaded glass windows etc... and we had seen Taliesin west a few years back. Walking though the home in WS he used plywood as a major construction material. No stain. Guide said it was a fairly new material and he wanted to experiment with it. Since it was in the country all the windows are clear glass so you can see the landscape outside. Just a departure from his early work and what he may be more known for. Brian
