I was a bit bored yesterday so thought I'd make some rivers and roads for DBA.
4mm cork tile
permafilla (for river banks)
Very basic- each section is 4cm wide x 30cm long. They look reasonable though.
Do I need 8 road sections? Not really, I've done 2 each for dry/desert boards and arable terrain for myself and 2 for the club. I'll eventually get round to making some rivers for the club but wanted to experiment with first.
