So where does all this stuff come from then?

I can't draw. That seems to be the main problem. The upshot of this is that when I want to convey to a client what their jewellery is going to look like it's generally easier and quicker to make something in silver rather than to present them with a drawing and watch their puzzled face as they turn it this way and that in order to try and make the incoherent scribbles on the page look like a piece of jewellery.
Making something physical also brings a benefit to the client as they can then hold and wear the piece. Often a ring that looks great on the page just doesn't work on the finger.
This process has left me with a box half finished pieces and ideas in development and, once ina while, when I get the chance, I dig one out and finish it up for the Rogue's Gallery.

In the box, I also have pieces that I set up to cast for clients. This is a time consuming process but, once the mould is made up, it's relatively quick to make a second piece and so it makes sense to run a few more off the mould rather than leave it languishing in a draw for the next 20 years.

I also use the Gallery to sell pieces that are no longer part of the range and those I've been left with by wholesalers who tend to drop a line just when you've made up six months worth of stock!
