Any of my fellow O Gauge fans use paper as a medium for building structure models? I started building scratch paper models in 1979 European prototype HO scale for Marklin trains. Now I model in paper for O gauge American 1950's Era. I would love to see some photos. You can build an entire city in paper for less than it would cost you to buy one plastic kit. This is my Christmas layout. All the buildings are made from scratch out of paper.
