I am a constant fidgeter, so I'm scrolling through Facebook and forums a lot just to do something with my hands. And I see a lot of people wanting to get started with airbrushing asking the same questions. With me being the know-it-all that I am, I repeat the same answers pretty frequently but always off the cuff and always missing something of value. So I have decided to collect my thoughts all in one place so that I don't leave anything out next time!
