I came back with 5 A4 sheets of white 5mm foamboard and a new project was born. I need 15mm buildings that I can use for SCW, Mexican-American War and modern skirmishes in Central America. So pretty generic white buildings with terracotta pantiles it is then.
Everything so far is cut from just one of my 5 sheets.
I nearly forgot the chimneys; I found some inspiration for them on the Empress Miniatures site, "Rustic Chimneys". I just need to stick on the corrugated paper to represent the pantiles and then I can paint and base them.
