When make up is airbrushed on the effects of what it does to the subject can be really drastic. Take a woman who has flawed skin and airbrush a light foundation onto her face and you now have a woman with perfect skin. The great thing is that the foundation is light weight and barely noticeable. Airbrush makeup has been able to take a woman that is plain and turn her into an exotic beauty with the right application of certain makeup. It is for this reason that the bottom feed is also referred to as a siphon feed. Since the artist can attach the cup to the bottom of the airbrush the colors can be changed quickly by using different cups prefilled with the colors needed. Airbrush art also uses airbrushes with a side feed. The side feed has a cup that mounts on the side. 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. If you rush you could end up messing your stencil all up. Another great way if you are doing this at home is to allow the design to dry then turn the shirt inside out and throw it into the dryer for about 40 to 45 minutes on the highest heat setting. After this your design will hold up to laundering. If you use a paint that does not require heat setting then you should still set the design.

While an experienced airbrush artist may know this a beginner may not, so it is worth mentioning. When doing airbrush art on skin make sure you are using airbrush paint that is designed for the skin.
