After adding all the polystyrene I wanted, making the ponds and the tunnels, the next job was to mod-roc all the embankments etc over the polystyrene. I found that while it is a rather dirty job, it is well worth it. After leaving overnight, a lovely hard shell made me feel that the whole method had worked and made things less vulnerable.
I have also made the river bed higher, it just looked too deep. I filled it in with polystyrene sheet, after making a template, not an easy job, but I am happy now.
I have over fifty trees and many buildings off previous layouts that were broken up. This includes a farm yard scene, which I have placed on the layout to see what it could look like, although I would repaint the buildings.
I now consider the basic scenics on both viewable boards complete.
Board one
Board two
Farm placed on Board two
Note that I purposely put the resin farm on the board without the controller etc. This is to even out the weight across the two boards.
Next job is to undercoat the whole viewable layout.
