Practice spraying the airbrush at your cheap surface while you learn just what pressure is needed where. If you are using a double action airbrush you should be experimenting to see how far back gives you how much paint spray. Once you are comfortable using the airbrush then you should work on creating shapes with your airbrush. Some blog sites such as Shout Post and Tblog actually show your blog posts off for you to other bloggers. This helps to get your blog some traffic. If you choose a blog host that does not do that then you should look into some blog traffic exchanges. After all what good is the blog if no one is seeing it? Airbrush art in the 1960s made its way into the music world. Album covers were done using airbrush art to create the whole hippy style images. The wild psychedelic artwork that was popular with that era were done thanks to the use of airbrushing. Tie dyed looks and large hippy flowers and even the peace signs were making their way onto vehicles during this era. A tattoo artist will rub alcohol on a person's skin to kill clean and kill germs prior to beginning to start a tattoo. In this case you are still going to use the alcohol but for airbrush tattoos it is to get rid of the oil on the skin and not to sanitize an area for a needle. Once you have removed the oil from the area the airbrush art tattoo will stick a lot better. This feed is great for airbrush art designs that call for fine detail as the gravity feed uses less air pressure. The less air pressure means that you can use slower movements when airbrushing. The bottom feed is where the cup is mounted to the bottom of the airbrush and the paint is brought up via a siphon tube. If you are doing a stencil for say a dog then you would want to take your time and make sure that the eyes were the same size, the nostrils were cut out shaped the way they should be and so on. If you rush you could end up messing your stencil all up. The stencil is to aid you in creating your airbrush art and is a big part of the art process.
