When I'm in here sewing there can be as many as 10 switches/appliances to turn off. As I leave the room often during a sewing session, I decided to protect things without turning off. All computers are on heavy duty surge protectors that can withstand a lightning storm. Most of the outlets are behind something so there's lots of surge protector/power strips. Makes it much easier to turn off iron, lights, etc.
A friend who doesn't close her rotary cutter and cuts toward herself make me and many other nervous. When she's here, I set up a cutting station next to her sewing station. So she rarely uses my larger cutting station. And I do close her rotary cutter if she leaves it open in my territory. I respect her right to be different, at her station.
