Hey guys! I'm one of the cardmodels.net refugees that have recently joined the Zealot forums. I'm trying to catch up on the vast number of interesting threads over here at The Gauge, and just found this one. Cardstock structures seem like such a perfect match for model railroading, this thread really shows that potential. Wow, all you guys who built the ScaleScenes freight house did a great job! If you like their models, be sure to also check out Clever Models. They also offer card models of North American structures in N, HO, O and S scales. Like ScaleScenes, they have excellent graphics. There is also a British outfit, Metcalfe Models. While their subjects are in British architectural style, some are generic enough to work in an American layout. Oh - a note on humidity. I am an American living in Shanghai (China), which is about the same lattitude as New Orleans, and has similar weather - extremely humid. I have card models in my apartment that are now about two years old, they have not warped. Other card modelers have reported no problems under varying levels of humidity as well, so you probably don't have to worry about that. Keep up the great work exploring the potential of card models!
