Sue, I'm sorry to hear you've not got any sales yet- it took me a few months to get my first sales, so I'm sure you'll be in for a sale soon. I have my fingers crossed for you.
I'm at the stage of spending more time on etsy trying to sort my shop out than making the jewellery too. However, I notice you only have a few items in your shop and my first 'boom' happened when I added about 70 items to my shop over a couple of months. I know people do rattle on about the magic 100 items, but going from about 10 to 30 to 100 items in my shop over a few months, my sales rocketed (loosely speaking!) from about 1 every couple of months to about 3 a month for a short while.
I would concentrate on populating your shop a little before the holiday season, perhaps with items in a price range- low to medium price, for example to cater for people buying gifts of all prices.
I think this photo is great too:

Don't lose hope- I think your work is wonderful.
I do not mean to seem ungrateful for my number of sales if it has come across this way. It just feels like a lot is going wrong for me at the moment, and making a sale every 2 weeks or so does not speed me towards my goal of making this a permanent job for myself, nor even being able to pay for my poor luck, like fixing my car or fridge. I know those dreams might be the ones of pipes, but we all need to have an ultimate goal- and I'm sure we'll be heading towards that dream at some pace, just needs to be a little faster, right?
The best of luck to you- and let us know when you get that first sale :)
