Haha Gabrielle,
You are a VERY lucky one getting a sale on their first day. I mean, I was even lucky getting one within 2 weeks of opening. You really need to take sales in the beginning with a grain of salt. I'm almost four months into selling on etsy, and I'm almost at 20 sales...not saying that's you by any means :) this is not everybody. Obviously we are selling two different things. I'm selling upcycled vintage and you're selling jewelry. Two COMPLETELY different markets.
I would suggest if you're using that wicker background, make the direction of the wicker all the same way to create cohesion in your shop. A lot of people use white backgrounds (fotofuze.com is really helpful)
I would also highly suggest looking into SEO, the sooner you learn about it, the better for you and for your sales-

Dire message me if you need anything else :)
