Host David Popp shows viewers how to build realistic scenery around the high embankments of the HO scale (1:87.1) East Troy Industrial Park project layout. In this instructional video, you’ll learn how to use foam board, packing peanuts, and plaster cloth to create a durable base for additional ground cover and fine scenery materials. It also offers tips on preparing the layout and protecting your track and backdrop when working with plaster.
