Saw this link on the paper model building forum. These models are typically O or HO scale but can be easily scaled down. They look pretty good with respect to weathering and accuracy for their building types. http://www.clevermodels.net/
I've always wanted to try out their sheets of siding and roofing and you just motivated me to get some and try it. Thank you very much for posting.
We also have this topic in our Inspection Poit: http://www.trainboard.com/highball/index.php?threads/paper-and-card-structures.53929/
I think we also had a TrainBoard Group. But that is in "storage" while Charlie works at finding a way those Groups can be integrated into this software.
I see that building flats is the main theme on that thread and I'm going for the actual 3 dimensional building. I'm ordering some textured sheets from Clever Models. I'm thinking of using scale lumber along with the printed card stock. I'll post my resulting structure effort.
