Do you do any work with Upholstery?
Not personally, but I know someone who is an upholsterer. I thought of asking him if I could become an apprentice upholsterer, but haven't yet.
Do you think it pays well to do it as a career?
I would imagine so. Upholsterers are very talented. In London in the 18th century they often worked as interior decorators, dealing with the whole room.
Wow, so they did less work as time went on haha. Is anyone credited with starting the craft?
I don't believe it was any one person, but the very word "upholstery" is from the Middle English term "upholder", meaning a tradesman who held up his goods.
