I made the upper level.
I laid out the track and some accessories for fitting. I’ll need to remove the track and felt as I complete the five rail track sections. I’ll install the carpet padding on the upper level at that time. Here is what I bought. I’ll need more, but I couldn’t fit the large roll in my car.
I also need to decide how to finish the side of the upper level. I’m thinking about a stone wall in spots. I may try printing it with my computer.
