There's a question that I think most makers of art or craft get asked quite often, which is "How long did it take you to make?". I always find myself at a bit of a loss as how to answer, because it's not as straight-forward a question as some might think. For me, some pieces that I've been making for a while can be made in several hours. But that's not really the answer to the question. There are the hours, and sometimes months (or longer!), of turning over a design idea in my head, working out how it would work. That's usually the beginning of every design - lots of thinking about the details of making, what order the pieces would need to be soldered in, what thickness the wire/sheet/chain would need to be, what metals or plating would be involved, what tools would be needed, etc. I like to think it through before starting. Then for a piece that's being made for the first time, there are the mistakes - sheet too thin, sheet too thick, need more of some material that I don't have, problems with the order of soldering, etc. When the piece is finally made, then the small adjustments can continue for months or longer. They may not be visible on the end piece, but they will be small improvements that make it quicker or easier or less costly to make the piece. Then, after perfecting the process and the finish, only then can I say "now I can make this piece in X hours".
To illustrate, I made a series of oval pendants (now at Jam Eton) and I knew what I wanted them to look like and I also knew that I wanted them to work as a series. Not because they need to stay together, they don't and they are separate entities, but I wanted a certain cohesion between the pieces. I like to have an aesthetic continuity that makes it feel like a collection. Anyway, first I made this pendant:
Here is a photo of just some of the attempts, including too thin, too thick, too big, too small, too hard (working out how many times and when to anneal) and so on.
