I saw your Keshi necklace Dawn, and I was very, very tempted! I don't often buy finished pieces, for some odd reason loose pearls are more fun for me, so I was torn between yours and more loose ones. Then it was too late, yours had sold.
I sell on ebay as well to keep me in money for buying loose pearls so I don't have to dip into the grocery money

I can tell you a little bit about running a web site.
I got my 'space' at Startlogic for just under $100 a year, my 14 year old son built it and made it simple to upload so I don't have to write html code (I get a bit lost when I try).
I think a good camera is a must, with a good macro or double macro setting. Mine is a Fuji Finepix S9600, but there are lots to choose from (maybe too many). Experiment with lighting. I prefer daylight, but just when I got it right for sunny days the monsoons came, now I prefer bright cloudy days but the sun is back.
Selling on ebay is a lot of hard work, though I've started using Turbo Lister, which means if I ever really had time before Saturday I could prepare my listings early, or if ebay pull your listing for putting earrings in the necklace category you don't have to measure everything again (yes, I really did that!) lol.
