painting Yorkshire stone I pointed out that I'd accidentally bought 7mm scale plastikard as it "looked right". Well I've now picked up a sheet in 4mm scale and as you can see the stone are a lot smaller.
I'm actually worried that the 4mm stones are a little on the small size, but I think they'll do for the small single storey workshop I'm planning. The 7mm sheet still looks promising for the large factory building though, especially as it will be further from the viewer.
I'm slowly running out of excuses not to do some layout building so hopefully it shouldn't be too long before there is some sign of layout progress beyond a plain piece of MDF!
