Mildly Amusing

Today I did more online reading about building your own door frames, and for fun, installing pre-hung doors.  I also watched a handful of videos of installations.  The first thing they all said to do?  Put a level on your header, and make sure that it is, indeed, level before you attach your new door frame to it.

Header?  Yeah.  I don't have one of those.

I can see clear through to the other side, no obstruction .  Guess I'll be doing a bit of retro-fitting... Probably not the last time.
