Step 1: Take the raw MDF and very lightly spray with matt black - just a dusting really so that some of the wood colour shows through. Hopefully this pic shows what I mean.
Step 2: Drybrush with any dark brown. I used VMC Leather Brown.
Step 3: Drybrush (very lightly!) with a light cream colour. Here I've used VMC Dark Sand.
That's it! All 12 sections took me less than an hour.
Step 4: Glue the fences to the bases.
The gate sections have subtly different bases and I like my gates to be slightly open as it makes them easier to spot at a glance.
Step 5: Apply sand and grit to suit your basing preferences.
Step 6: Paint the bases. I bought a tester pot of emulsion as it's way cheaper than using VMC etc. I think it was called 'coffee shop' but was fairly similar to GW Graveyard Earth.
Then I highlighted it up using my usual VMC Flat Earth, Gold Brown and Dark Sand colours.
Step 7: Finally, decorate them - I always really enjoy this bit - in fact I probably spent more time on the flock and foliage than the painting.
That's 6 feet of fencing done in double quick time. Now back to that Signal Box :o)
