On the wooden board base I drew an outline of the shape I wanted the mountain to be. I took into consideration the placement of other things in the set, such as house, as to where the outline would go. After this I put a rectangular shaped area of foam on top of this and sketched the same outline onto this. The shape in the foam was then cut out using scissors and placed on top of the original outline on the wooden base. I repeated this step multiple times, however each time a new piece was cut it was made slightly smaller in width than the previous. This was so that when set on top of the previous piece the mountain would appear to go inwards, resembling mountain rings on a map. It also allowed the mountain to not be just a straight, vertical line, and gave some more definition - mountains are never perfectly smooth.

Using scissors, I cut small - medium pieces of modrock from the roll, soaked it in water and then applied it along the outside of the foam of the mountain. The modrock requires to me sort of massaged into the exterior, forming a kind of clay like texture.
