Any guides to trimming eyebrows

[pumpeduppecs]

Been using castor oil and I now have thick eyebrows I need to trim them I wanna trim them as aesthetic as possible should I do a downward slope towards my nose? And how should I trim them?

trim them down to 1/8th of an inch (red guard) and pluck them in line with your nostrils
