The ‘flat’ bits of grass were always intended to be a temporary stopgap, this is the original bit by the tunnel:
Work started by removing the old ‘grass’:
A template was made of the area from thin card (250g/m²):
A 25mm thick section of insulation board (Kingspan or Celotex) was marked up and glued to the card with Evo-Stik:
The board was roughly trimmed with an old kitchen knife to fit the card, the the top of the mound roughly shaped:
Then smoothed with a surform (this is a messy business!):
The use of the card “base” allows the edges to be smoothed to almost nothing.
Check it fits:
A quick coat of brown(ish) paint to avoid any of the white showing through:
The mound is then covered with a ‘grass’ base. I’ve used Javis ‘Rough Terrain Mat‘:
The mound is then stuck to the layout, and finished off with various ‘turf’ scatter, which helps to blend the edges of the mound into the layout.
