Next up on the game board list of things to do is the roads. One option I'd seen was cork board but I didn't have access to this so undecided to try Poundland cake board. It's about 5mm thick and made up of dense cardboard I believe. It was a nightmare to cut with a craft knife but I eventually cut out the 3 sections I needed. 2 straights and one turn for my 3 urban tiles.
I beviled (I think that's the right word! ) the sides so they slant down and cut into the roads some pot holes and cracks.
Next up will be undercoating and textured paint on.
