You poor thing:>) Put on a roomy shift/caftan, etc. a pair of comfortable shoes; pack up your goodies in any tote bag or purse that will hold you materials; and take whatever machine is most comfortable for you to carry and use.
Most important, arrive early and sit right up front as close as possible to the instructor. You've paid your money just like everyone else and you want to soak up every bit of information about the New York Beauty Block. Doesn't matter if you're a newbie or an old pro. You're all there because there's something about this particular block you all want to learn.
Good luck and be sure to post pics as you progress.
