The trigger is pressed down for the air and back for the paint. Now when it comes to the feed on the airbrush there are three types of feeds that you can choose from. The type of feed you choose will also depend on what you are doing as well as what you are comfortable working with. The gravity feed is a top mount cup that uses gravity to pull the paint down into the airbrush. You can heat set by placing a protect cloth between the design and the iron and ironing the design or you can turn the material inside out and place in the dryer on high heat. If the acrylic does not require heat setting on fabrics then you should still protect the design from fading when washed. To do this place the clothing into a sink of cold water and salt and allow to soak. The nail art masks are reusable masks that have an adhesive that does not leave any residue on the nails. Of course if you are really creative and very good you can freehand the airbrush art right onto the nails. If not then take the time and invest in nail art stencils and masks. The paint that you will use when doing airbrush art on nails is water based. It does not matter if you can draw or not. There is no need to be able to free hand you art work either. Stencils can be used to airbrush art on to your automobile just the same as any other surface or project. The art that you create with airbrushing is only limited to your own imagination. There are plenty of places to acquire stencils or get design ideas so that you can create your own stencils. You can go with a nice mural on your wall to give a room in your home an artsy feeling. Or you can scale it down and just airbrush a border at the tops of the walls. Airbrushed borders look more decorative than glued on paper borders on your walls. Thus the interior of your home can be your canvas for your airbrush art. The video features Air Brush Action's Teacher of the Year for 1995, Debbie Eastlack.
