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. Thus like the needle you will be unable to create desirable airbrush art. Both the needle, air cap and head assembly can be purchased at almost any craft or hobby shop that sells airbrushes and airbrush parts. The airbrush trigger is what allows you to actually operate the airbrush. In a single action airbrush the trigger controls the air flow. The work area is very small and the artist has to have mastered the techniques involved with airbrushing. One main problem that beginners face is over spraying. Over spraying is when the artist sprays outside of the area in which they are trying to spray. When working with nails you do not want to end up airbrushing the person's fingers. While even this seems primitive compared to what we can do with animated movies as well as for airbrush art, this method did pave the way for both the improvement on animation and airbrush art. The 1960s brought us even closer to what we now know we can do with airbrushing. Airbrush art in the 1960s made its way into the music world. Once you have mastered your skills in micro airbrush art you will be amazed at the amount of detail that you can place in any airbrushing project. This ability will help set you apart from the rest of the competition and allow you to reach the top of the airbrush art industry. Becoming a truly renowned artist in your trade is dependent upon just how much detail you can capture in your work compared to other artists. But as long as your project is made from the above material you can use water soluble acrylics for your airbrush art designs. Depending on which brand of acrylic paint that you go with, you may need to thin it down so that it flows freely through the airbrush. Also some acrylic paints require that they be heat set if used on clothing.
