It is the usual modular deal that people do with their roads. "Why not snow?" you ask, no doubt disappointed - Well the reality is that all these new genres we seem to be getting into every other week (seriously, they just hooked me into 28mm ww2 as well, ffs) mean I need what I make to serve in more climes. Put on a white table, these will be pretty realistic for raised roads, later in the day after a light dusting of snow - ie the snow melts off the roads.
Edit: Adam reminds me it is traditional to actually say how they were made, on a wargaming blog. Nothing too fancy - they are actually made out of foam-board (bought from Warehouse Stationary) that I used because I had it lying around and it of course cuts very easily and is light. That meant I had to edge it with masking tape. The surfacing, is of course 'No more gaps' (or Bostik Fill a Gap) and sand + housepaint. Then scenic stuff, obviously. I actually put 'Magic Wash' on this to see if it would pick out a little more of the detail and make it even more durable - it half worked. Magic Wash can be made from 'Johnson's Klear' in NZ (ie floorwax) in NZ and I put it right over the scenic stuff too. The same job could be done with thinned PVA but I like to hope that the paint wash effect might works, which it did, sorta. The more usual way to make them is with strips of wood, or that railway basing foam that Acorn models does (by woodland scenics), which is precut into lengths.
Now the other 'new big thing' is of course lots of new trees. Hope the ebay ones get here soon, so I can get started on them.
Thanks for reading.
