Katie, jewelry is a very saturated market on Etsy (and everywhere else).
So you have to work hard to stand out from the crowd.
What exactly, for instance, do you mean by "I promote all the time"?
Do you have a marketing plan? Did you find your target market and are you promoting directly to them (= marketing)? Or are you posting your listings randomly on social networking sites (not to your target market, but to your friends and family)?
Having your items found involves a lot of work.
