I am not a member of IATSE yet, but I intend to join when I am done with school. My husband is an IATSE member as a stage hand. But I am a little confused... you are in AZ? I beleive you would want to join local 706. There are only 2 major locals for makeup and hair, and the West coast local is more stable. 891 is Art department. Also... you ventilate? Where did you learn? (just curious)
