How do you move the inset at 1:46 to the right to cover the faces??? That part should really have some kind of explanation.
Covering the faces to the right of the inset isn't explained.
I figured out how to make it look right switching to vertices and doing some extra steps but what you did seems to be only one step and it was covering the faces and I just have no idea how it was done that quickly.
Also, what was the select similar operation meant to do that was before this?
