Knowing your own worth.

I am working on a piece today that I hope to be able to sell as a Fine Art piece and the difficulty that is haunting me is how do I price something like that. I have clocked up 13 hours on it already. If I was scrubbing floors or filing papers for a living the minimum that I could expect to get in this country for that time is £80.34. I am only 1/2 way through this project at the best estimate, so I'd be looking at £160 just on the creation, that doesn't even take into account cost of materials or and fee that a seller might require. The best I could look at for commission is 25%, most places charge a lot more. So when I release a piece with a price tag of £250+ what will people's reaction be? I guess most people will laugh, but then, wouldn't you want to be paid for your time? Where are the people who paid a fortune for a spirograph picture by Damien Hirst? Embroidery doesn't hit the same market that paintings do. I remember watching the play 'Art' by Yasmina Reza (and thoroughly enjoying it) where friends fall out when one of them purchases a white painting for a silly sum of money. This always comes to mind when I think about selling my work. I wish that I could sell my work for a sum that would pay me minimum wage. When you look at art do you see the time and skill that goes into a piece or just look for the gimmick? (OK now I'm singing a chorus from Gypsy) When I release this piece I will charge what it is worth in time and costs, I won't be able to put any value on for art or skill though. Who knows if I'll be able to sell it? Probably I won't, maybe I'll just end up with a house full of beautiful pieces but still no income. Maybe I'll find an art patron who loves my work because it isn't 'off the wall' and zany. Maybe it's all just dreaming.
