It is the time of year when I launch myself into designing a new set of very tiny little buildings. I design them in a 3D CAD program and that is what these images are taken from. Now this little building in the smallest size I offer it is only .84" high. Yes, that is right less than 1 inch tall!!
So when things get that small no way do you want to have to handle a ton of tiny pieces so the goal is to make it fold up from as few pieces of cardstock as possible. I create puzzles in thousandths of a inch increments
