This feed is great for airbrush art designs that call for fine detail as the gravity feed uses less air pressure. There are several ways that you can get your airbrush art seen. Most of these ways will actually cost you nothing. The use of the internet has made it where you can show your work to the world for free. Almost everyone on the internet has started using a blog. Well you should be no different. Get yourself a free blog and start showcasing what you can do. You can go with a nice mural on your wall to give a room in your home an artsy feeling. Or you can scale it down and just airbrush a border at the tops of the walls. Airbrushed borders look more decorative than glued on paper borders on your walls. Thus the interior of your home can be your canvas for your airbrush art. All this can be done if an artist takes the time to learn micro airbrushing. There are couple of ways that an artist can learn how to do micro airbrush art.

No matter what material you go with make sure that you remember to cut out your areas slowly. By taking your time you can make sure that everything matches up the way it should.
