Not stunningly impressed with this. The fishing wire wasn't keen to be stuck into the holes. I think there's supposed to be 4-5 wires, but this was testing my patience as it was, and this from the man who has built buildings from single blocks of card in the past.
Anyway... stuck in with UHU and a three layer paint job (grey/green/brown) to try to make it visually disappear and not look like a set of gravestones. General bedding-in to do. This may get replaced.
