I get mine threaded by this cute South American boy at the salon where I get my hair did. But since he is major expensive (I am cheap, what can I say) I wax and trim myself between touch-ups. He is very expensive but the best I've ever had (was born with unibrow...

) so like I said, I just clean up underneath myself with wax.
I tried to shape my brows just ONCE with wax myself.
OMG took near all the hair off of my face.... wasn't pretty at all.
