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. The images they create are just a vast as the surfaces that they are airbrushing them on. This is why airbrush art fits for just about everyone around. Classic paintings can be airbrushed onto canvas to give for great wall art. With airbrushing the paint goes on to the canvas more evenly than if it had been hand painted. Depending on the type of airbrush art you are doing will determine the type of airbrush that you need. When doing airbrush art on nails go with either the Iwata HP-A or the Iwata HP-B. These are great for airbrushing nails. Even if you do not go with the Iwata though remember to always go with named brand and never use any knockoff airbrushes. While under the supervision of an expert you can quickly learn where you are making some mistakes with your work. Expert instructors include Peter West and Pamela Shanteau who hold classes at the Learning and Product Expo: Art for beginners through to advanced. AirBrush Action offers their Airbrush Getaway Workshops that run from a one day class to four day classes and are located in Las Vegas, Nevada. When you first try using an airbrush you need to use a cheap surface that you can just practice with. A simple black paint with work for this. No need to buy additional colors. The only thing you need to be doing is experimenting with the airbrush. Get used to how it works and feels in your hand. Practice spraying the airbrush at your cheap surface while you learn just what pressure is needed where. The use of talc powder after the design has dried will help to keep oil from building back up and thus still ruining the airbrushed tattoo. Nails should be clean and buffed prior to beginning. Buffing the nails will give for a rougher surface for the paint to cling onto. Prior to actually airbrushing the nails, a base coat should be applied.
