Re: Theatrical Mic Attachment
As Tom and Jordan have already said, you'll struggle to make it stick after make-up, so you definitely want to be sorting the microphone first. With some performers who sweat more than others, you might have more success putting a piece of clear double-sided tape (wig tape, etc) on the skin, then placing the microphone on that tape, and then putting a slightly longer piece of Micropore or Transpore over the top, overlapping the ends of the double-sided piece. It'll be firmly stuck for the show then, but the downside is when you come to take it off!
However, unless you're really struggling with feedback or the performers are wearing hats, I'd aim to put them all in the hairline, and only tape to the cheek as a last resort. If the performer has plenty of hair, the easiest method is to make a headband out of thin elastic, tie the capsule to the front (and the cable a bit further back) and then position it on their head so that the elastic is hidden under the hair, and the capsule is sticking out in the centre of their forehead. Obviously there are plenty of other ways to secure the mic in their hair if you have enough time available.
If you're not familiar with the various techniques, it might be worth spending 15 minutes looking at the link below so that you can see photographs of how to use the different methods.
