Also the airbrush paint will get them wet and they can start to tear. You will need to keep the original design so that you can refer back to it. After you have made copies of your traced design start cutting out the areas that you need to cut out. Then place the home made stencil onto your project and begin to airbrush your project. Show some pictures of your work and tell your audience how you created that design. Talk about the paints that you use, the types of airbrushes and so on and so forth. By discussing your techniques and sharing your insight you will show your audience that you are an artist that knows what they are doing. The prep work that you do will be determined by what type of surface you will be airbrushing. The prep work to the surface will ensure that the paint sticks to the surface and that nothing is interfering with the airbrushed design. For airbrushing t-shirts, sweatshirts, denim and other natural fibers you first need to wash the material. Larger airbrushed areas are better done with the external mix. Since with the larger dot pattern you are able to spray more areas in less time. Airbrushes also come in single and dual action. This refers to how the airbrush functions. With single action only the air is controlled with the trigger. The trigger will control the air and the amount of paint that comes out is determined by the needle adjustment on the back of the airbrush handle. In a dual action airbrush the trigger controls both the air flow and the paint flow. Beginners should really take the time to practice on how the trigger works so that they can perfect their ability to airbrush. Your airbrush will have a back lever as well that acts to shut off the air flow and paint flow when the trigger is released. By acquiring the skills needed to do micro airbrushing the artist can capture more detail in their airbrush art on the model car. Imagine being able to create realistic eyes on a dragon you just airbrushed onto the hood of a small model car? When a person looks strongly at your artwork on the hood of the model car they can really see the capacity of the skills that you have as an airbrush artist.
