Better Way of Hiding Lav Mics

Anybody got a better method of hiding lav mics under lapels / shirts and what not. We've just been taping them with a bit of gaffers tape but when subject moves you end up hearing the clothing rubbing up against the mike. There's got to be some trick short of using a shotgun. I've seen the little pin on things on b&h's website but they seem like they would be bulky and visible through a shirt and still may end up rubbing on clothing. Any suggestions.


thanks,

Michael
