How do you add an edge around a hole? I was hoping someone a little more experienced with Blender could help me out here.
I'm working on making a low poly helmet when I encountered an issue, I would like to add an edge where I have drawn the red lines but have no clue how to do so.
I would like to preferably place it parallel to the existing hole.
start with


F to fill


I to inset


O to outset


X to delete faces
