Card Models are wee airplanes and ships and buildings and buses and whatnot. They aren’t made from plastic, though. You download images somebody created with CAD software and cut out all the parts, then paste them together. Then, most important of all, you don’t leave them in the window where your cat likes to sleep. He will surely sit on them, and you will weep, and gnash your teeth, like the sad wretch you are. But I digress. There are far more card models out there than you will ever have the time to build, and this list is but the tip of the googleberg. I find some of them amusing, for example: ” The Lint Hotel in Cologne has a model of their building.” ironically, you do not build it out of lint, or cologne. Many links are dead, but from a list this massive, that is no surprise.
