u/ModelAirportDiorama

I have been in the model airports hobby for a while now, but have yet to make a model aircraft fully out of paper such as the one above. How do people go about creating the templates for these models? I would like to build a very specific plane that does not currently have high-quality templates online, so am looking to design my own templates. Any help advice appreciated.

This is a 1/500 build of a fictional US air force base.

This is my Lukla Model Airport in 1:500 scale. For those wondering why an Aer Lingus aircraft is at this airport, it is because I don't own another turboprop aircraft that would be better suited. If you would like to see more angles and some build footage, you can watch this video on my youtube channel: https://youtu.be/jPn6WQ0gSho
