The method believed to be used in this primitive form of airbrush art was the use of a hollow bone in which to spray the paint out of by blowing through it. While this is a very primitive method compared to modern day forms of airbrushing, it does still work. Take a look at children's airbrush art kits that require the child to blow through one end of tube to create the airbrushed art. The stencils are made from different material depending on what the stencil will be used for. But no matter what material your stencils are made from they all have to things in common. One the stencils can start to get expensive purchasing. Secondly you are limited to only creating designs based on the stencils that you can get your hands on. The art that you create with airbrushing is only limited to your own imagination. There are plenty of places to acquire stencils or get design ideas so that you can create your own stencils. If you do create your own stencils for airbrushing your automobile do not use paper to create your stencils. Automobiles need lots of paint and this will damage paper stencils rather quickly. For the paint you have an internal mix or an external mix. The internal mix is when the air and the paint both mix inside of the airbrush. This will create a atomized fine dot spray pattern. This makes the internal mix a good choice for fine detailed work in your airbrush art. The point at which they come together is in the head assembly. Why You Should Learn Micro Airbrush Art Micro Airbrushing is a valuable skill for all airbrush artists. Being able to do micro airbrushing will allow for the artist to create a more realistic and more in depth detail on all small areas of their airbrush design. It is in these small areas that a lot of artist miss the chance to really define the details because they are unable to fully create the detailed area. The paint that you will use when doing airbrush art on nails is water based. A bottom coat and a top coat are what protects the water based paint from being damaged. You will also need to spray a light coat of what is called varnish between the artwork and the top coat. Varnish is just a water based clear coat that will protect the paint from getting brush strokes when you apply the top coat.
