Basic Scenery landforms can be built very fast using cardboard strips and plaster impregnated cloth. The mountain below was formed in just over an hour and is approximately 2 x 4 feet.

For my last layout I used styrofoam for scenery. I found that approach to be expensive, time-consuming, and messy. The cost of cardboard strips is essentially nothing. Additional money can be saved by using plaster and paper towels instead of plaster cloth. A 25 pound of plaster from a DIY store like Home Depot is very inexpensive comparatively. Many modelers use Hydrocal or dental plaster but in my experience, regular of Plaster of Paris is inexpensive, readily available, and works just great.
List of tools and supplies:
- Hot Glue Gun
- Cardboard Strips 1″ Thick. I buy mine from Micro-Mark to save time and aggravation.
- Clasp Stapler. A good 25 sheet capacity stapler from an office supply store will work just fine.
- Plaster Cloth. I used Micro-Mark again for this also.
- Large bowl or small bucket of water for wetting plaster cloth
- Scissors to cut cardboard strips to length and to cut the plaster cloth
I start with the vertical strips and attach them every 4 - 6 inches along the backdrop using hot glue to begin defining the landform. Pull the strip over a piece of benchwork to make it more flexible.

The horizontal strips are then woven in to provide strength and further define the shape. The joints are stapled using a clasp stapler. This will go much faster than using hot glue.
Using the plaster cloth is very easy. The roll is about 8″ wide and I cut it into pieces between 4 to 8 inches long to allow me to pick the right piece for the given space. Dip the piece into water just long enough to soften the piece but not so long as to allow the plaster to wash off. It takes about 1 to 2 seconds. Drape the pieces on the cardboard strip form and try to overlap in order to provide double thickness as much as possible.

After experimenting with the plaster cloth for a bit, I went crazy with the cardboard strips for a couple of hours.

Tips:
- Make sure the track looks like it was cut through the terrain. It is easy to base the scenery on the roadbed but the result will be unrealistic.
- Test clearances on corners using a standards gauge or your biggest expected railcar. Be sure to consider the thickness of any castings.
- Build the basic form with just a few horizontal and vertical strips then go back and fill in.
- Don’t be afraid to make changes. It is very easy to make changes at the cardboard strip web phase. Just make some cuts and lengthen or shorten the strips to suit.
- Tape the track work and protect the floor with plastic to avoid an industrial size mess.
The next step is to add rock castings and start bringing things to life.
