Don't know how well I fit into this question, as I'm trying to take my furniture making pro...
I haven't started selling my furniture yet, but am desperately hoping that there is a market. I'm almost at the end of my two year course in Fine Furniture Making, and will shortly have three pieces to sell. One of these is a table that I've ploughed four months into (never spend four months on a speculative piece: it is insane). I've gone down a very high-design, furniture-as-art route (we're yet to see how successfully), with the intent of being able to market the design, the story, the fact that it's a one-off as much as the piece itself, and thus command a figure that would pay me minimum wage for my time.
I need to get a lot quicker if I want to make furniture making work, probably do batch runs, standard products etc. I half expect my future holds a move into fitted kitchens or contract joinery, with the occasional furniture commission to feed my soul: bringing in enough furniture income to keep the workshop lights on is hard work, particularly in London.
Cheers,
Chris
