@MakersHour Q3: What would you be making as an extra in the bg?
A3: Well let's think.
As an extra, I would be hoping to prove my acting chops to secure a bigger part. So it would need to be something that didn't take much concentration, to allow me to express dramatic emotions rather than tongue-stuck-out concentration face. But also something that, if dropped to convey shock or horror, wouldn't be difficult to pick back up again.
So I'm going with simple stockinette hat in the round. Or possibly a slipper sock.
