Did you know there are upholstery cops that come by and make sure you're putting those tags on? They don't come around often but they do exist. I know an upholsterer who got fined for not having any. The stuffed articles act is Real Shit.
I got into upholstery because I went to art school and got a textile degree. I imagine you become an upholstery cop because you like bureaucracy. In Canada they're the TSSA- Transit and Safety Something Something. They regulate airplanes, busses, boats and roller-coasters. And mattress tags.
