It may take awhile but with the limitless supply of images and artwork on the internet it is sure to keep you supplied with some inspiration. Sometimes you just need to step back and take a breather to get your inspiration back. If you find that you are not getting inspiration no matter where you are looking then it is definitely time you stepped away from the airbrush art for awhile. When doing airbrush art on skin make sure you are using airbrush paint that is designed for the skin. Usually this will be sold as airbrush body paint or airbrush temporary tattoo ink. These are the only types of airbrush paints that are safe to use on the human skin. These paints will have a hard time staying on skin that is oily. You don't want to mar the wood only remove any rough areas. If the wood has been waxed or has a gloss coat then sanding this will remove this and allow for the paint to stick to the surface. Skin should be cleaned with rubbing alcohol to remove any oils from the skin. The skin's own natural oils will prevent the airbrush paint from successfully sticking to the skin. 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. So the choice is yours as to whether or not you want the handle on or off of your airbrush while you are creating airbrush art. Pay special attention to the threads on your airbrush. The threads are located on the head assembly and where the air hose connects to your airbrush. If these threads should ever become cross-threaded then you could end up with an air leak. So before attempting to do airbrush art on nails gain some experience with airbrushing on larger surfaces. 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.
