For those of you into modelling but are short on cash, I have a solution for you: paper models. They may not be as sturdy as plastic models, but they can be obtained online for free and just one ink cartridge has enough ink for around five to seven models, depending on the amount of pages the parts take up. Try this website for simple paper models (Fly'N Things -- Amazing Paper Airplanes, mostly airplanes) and then move on to even harder models. If you manage to complete a nice-looking model, feel free to post a picture of it in this thread with the website you got it from. Good Luck!
