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. 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. The gravity feed is a top mount cup that uses gravity to pull the paint down into the airbrush. 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. Most of the times you will need to heat set your paints so that they can be washed without fading or bleeding. There are a few ways that you can heat set your airbrush art onto the t-shirts so that it lasts. One way is all the design to fully dry then place a cloth over it and iron the shirt with the cloth between the t-shirt and the iron. 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. First let's look at how to clean your airbrush. One rule of thumb to remember is the type of cleaner you use will depend on the type of paint you use. Solvent based paints should be cleaned with a solvent based cleaner. All water based paints can be cleaned with water or a commercial cleaner designed for airbrushes. 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. Or imagine that no matter what size your project is, even the fine details are brought out to the point that they demand to be noticed. All this can be done if an artist takes the time to learn micro airbrushing.
