Cedar Was Used on Floors Too
Just for reference, I worked on the oldest Queen Ann in Olympia, Washington. Among my many projects was adding to the exiting floor and hiding old register holes.
Interestingly, the entire house was Northwest Red Cedar, including the floor. The finish was just amber shellac. Though the house was eight years old then, the floor was in pretty good shape. That, likely, was due to the shellac and it's ease of application throughout the years after the initial application.
The reason I have what you want is, I never lent it out before.
Scraps are a myth.
