Laura, I checked everything out in your shop including your wonderful "About" page. 2 minor things:
1. Since there are other PeachTrees, you might want to add "Designs3" in small type below the larger type at the top so they remember that they saw YOUR shop.
2. Now here's the really obvious one... You have only been open since July! Slow down, take a deep breath. Remember that the holiday season is coming up and you WILL make sales. It took some of us months to make our first and then zzzzzzzzzzz our second sales! Relax. Keep producing. But really, keep promoting. There are free places here on Etsy to promote. One is the Promotions team. Each time you list or renew something, or even just want to show it off, there is a discussion thread in that team to let you list it.
3. (added number) Join a couple of teams. Don't overwhelm yourself. Teams expect you to show up now and then and add a comment and help each other out, like this. There are specific jewelry teams. You might find one for earrings that suits you. I don't know. Look at all the team lists. Maybe one for your state or even specific area (I'm in one in southern Oregon and you can't get more specific than that!!)
Good luck, and good patience. I also hope you're checking out all the shops who are offering suggestions. It's a goodwill thing to do. Put them in circles. They will click on your and favorite your things and people will see them. Circles see Circles. Etsy is a big place. Put yourself out there...
