Hello,
I understand your worries, I’m dealing with the same at my shop
https://www.etsy.com/fr/shop/Vintagebrocanteuse I have a very new shop and had my first selling short time ago. I keep thinking that it will be better because I like so much my new work and I try to stay optimistic.
What I can share with you is that I keep working on the tags, the pictures and to compare prices to be sure to not be too expensive or too cheap.
Maybe it’s also helping to tell the story behind your shop, your product, why you do things, Instagram helps to share more personal things that can help your business activity.
Hope that everything will be starting soon for you and also for me 😄✌🏻💪🏻
