A nice little video, really short, on using a thin piece of foamcore board to make a small hill along a curved piece of N-scale track. Cut the basic curved shape, sanded down with rough grit sandpaper, glued to the layout bed with Liquid Nails, coated with brown acrylic craft paint, sprinkled ground foam, and sealed with water/glue mixture.

A super simple method, which I would imagine works on a larger hill or mountain just as easily. Itís been a method Iíve been considering for a start at one corner of my layout.
