1. Your photos could use a bit of help, but all in all they're pretty good!
2. Your descriptions should really sell your item! In the first line, put your eye catcher. Tell them how they absolutely CAN'T live without your item, where it would look great in their house, who it would be a perfect gift for. Then give the details (size, color, quantity) and describe it like there were no pictures to go along with it. Use short sentences or even better, bullet points. End with a link to that section in your shop so they can find similar items, a link to your shop policies, and a thank you for looking.
3. In your policies, stay away from negative phrases like "I am not responsible" - they scare people away. Stay upbeat, positive, and friendly, and make it clear that customer service is your priority! Explain everything, even the obvious. Think of any questions that they might have on your products, and answer them. The quicker and easier it is for them, the happier they'll be.
4. Get a facebook business page, a twitter account, an instagram, a blog - anything to help promote your shop. Advertise on blogs that you admire, that target your specific audience. Think smart - don't go for any ol' blog. Pick one that YOU would read - your target audience reads it too, then.
I hope this helps!
