Thanks KathieB for the terminology (board and batten - I had no idea!), link and smoke and mirrors advice I shall keep pottering about the internet now I know what to look for and work out which way I want to go
Thanks Wormwoodz for your suggestions. I've tried a low quality timber filament before (for other things) and sometimes it looks ok, and sometimes it looks very plasticy - like you said, not very convincing. I printed a chess piece that looked great, but tried a train track and it looked rubbish. I've ordered a better quality wood filament so will see how that goes, and if it doesn't look great will probably just go with plastic as you suggest. I'll keep you posted
And thanks Havanaholly for the pics - gorgeous house! I love the siding in the attic - very cute
