Also a good basis for making Warhammer and other gaming terrains
Step 1: Supplies
Styrofoam insulation board (Only because it is very fine grained and is easy to work with)
Plain Clay Cat Litter (unscented or any "extra" additives)
Sawdust (everything has a use) or if you want to buy static grass for model railroads.
Toothpicks (round ones are better)
Thin cardboard or card stock
White Glue (like Elmers)
Paints: Black, Gray, White, Green, Blue, Yellow other colors are optional.
Step 2: Sub Assemblies
I make this out of the foamcore board, cutting the edges down to a beach like profile.
Made from chunks of insulation board either cut to shape or chipped away with your fingernail or other tools.
Made from the toothpicks and sawdust layered on the top or small strips of paper for leaves.
Chunks of insulation board cut to shape then roofs made from card stock. Windows and doors painted on. Chimney may also be added using foam board or toothpics
Anything not covered in the above, like a shipwreck, treasure chest, mermaid.
Step 3: Base Construction
Trim more if desired for smoother slopes and edges
Step 4: Adding Main Rock)s)
Glue to the foam board where it looks best.
