Thank You all for your kind words.
In the mean time I started a new project to celebrate next year the Moon fiftyeth anniversary. I choose the Ken's Apollo Command Module. The first problem was the model's final dimension: I have to reduce it to one half. Therefore a lot of problems arose, mainly about which kind of paper, which thickness: I had to do more researches, more experiments, more tests. I had also to verify if the small details could be done as the design provides, and if not which metode could be adopted to approximate the result. I choose to start with the door of the CM, that concentrates all the problems that I can imagine about thickness, a bunch of small details, etc. Here where I am, with my test and the result is quite satisfying and if the next steps will go well, I let you know, starting a proper thread, but the path is still long, very long.
Best, Nando
