You must practice on actual fabric, since it has a different feel from paper. This is a stroke that goes from a wide line to a fine line in a short space and is that used most often by T-shirt artists. All your customers will want a name airbrushed on their T-shirts. Remember to keep your letters consistent. To achieve a hard edge, you must use a stencil.
Most airbrush work is a combination of free-hand airbrushing and stencil airbrushing.
This should consist of red, yellow, blue, purple, aqua, brown, medium gray, black, white and hot pink. These can be made from quarter-inch tempered masonite or foam board. Many T-shirt airbrushers work with one airbrush per color for ease of operation. All the airbrush hoses are hooked up to one compressor. Since you can use only one airbrush at a time, this system will not overload your compressor.
