I am using tweezers less and less for positioning very small parts like PE and even styrene. I have had tweezers launch so many small parts to places unknown!
I am more and more using sticky sticks- small sticks with a sticky adhesive on end. I make my own with a toothpick, with a tiny glob of poster tack on end. I place the piece in its location, and use my needle point tweezers merely to help nudge the piece into final position and hold it there till the CA sets (I do not put it between the tips of the tweezers).
