Hi Art,

I totally agree withwith Grainne. Yet having said that, I am a beginner and I'm using a hair dryer. I think its helping me to learn what the paint will and won't do on wet, damp, semidry, and dry paper. I think this is about experimenting and figuring out what works best for your personal process and style. Your aesthetic may be different than others. I feel that I will use the hair dryer in my process but eventually only in certain applications when I want to "freeze" or hold an effect or at times when I'm not looking to blend wet in wet or the dry down is less important for my vision to materialize.
