Does anyone trim their own undercut?

I really need to change my username.

Yes! Set up two mirrors so you can see what you’re doing. I tie my hair up then use a wide headband to make sure there’s no stray hairs that shouldn’t be cut. And also lay my finger along the line so I can’t go too far with the clippers.

Thanks @cannaethink! I'm feeling mildly confident.
