Sounds like you are wanting to be an artist of sorts using metal/welding, etc. as your medium. If so, you need to have some (preferably a LOT) of artistic ability, not just be able to weld, and an "eye" for what is good and what is not.

You may have been born with these artistic abilities, some are, others learn it thru art classes and school curriculum focusing on art. Some never get it. It helps if you can draw.

I am an artist blacksmith and work with a designer. Together we create beautiful things that our clients pay a lot of money for. We only work with high end clients and usually only in $$$ million + homes. Sometimes I make something 3 or 4 times taking days or weeks, often just so she (the designer or client (or both)) can SEE what it will look like. Then changes are made and we proceed.

The point is, what you think is beautiful someone else may not. If your market is a flea market, that is one thing. on the other hand, if you are wanting to REALLY have a business, you have to be able to make something that someone else wants and is willing to pay for. This is not always easy to do, but it is something that can be accomplished, over time.

Rarely will you be instantly recognized as an accomplished artist, metal or otherwise. It takes a commitment - on your part - of time, lots of hard work, some money, and education. Pay attention to the DETAILS!
