Smallish specimen pinning/spreading question

[Kondla, Norbert FOR:EX]

Given the size of my dainty little digits, I am able to do the thorax
pinching and consequent wing opening with my thumb and forfinger on things
the size of eryphon and even blues, altho I have not yet had the courage to
try this on really teeny things like Brephidium :-)

This may not be proper, but when wings are difficult to open, I pinch
the thorax with curved butterfly forceps.  As I said, it may not be
proper, and it may do damage I am unaware of, but it works for me.
