promoting on as many social media platforms as you can possible manage, and lots of word of mouth.
Also I’d check you spelling of Jewellery as you’ve used Jewelry in some of your descriptions. As this is a site for UK, sellers one would expect the UK spelling of Jewellery.
You need to show the chain up close so potential buyers can also see the chain and you also need a photo of the whole necklace not just the lovely flower pendent.
Remember potential customers can only go by the photo’s and descriptions, they can’t pick it up and look at it like in a bricks and mortar shop.
Don’t forget to say what the chain is made from and what type of clasp if any is used on the chain and a close up of that as well.
Hope that helps and all the best with your endeavour.
