Hi Sarah,
I just love your shop.. I love your banner, it really drew me in and made me happy. I think you have a great mix of quirky things - I felt less for the adjustable bracelets and pendants, they didn't really do it for me so much, but definitely LOVED the polymer and the felt items... yay! I liked them so much I just bought some paperclips from you!
Pricing: price remembering to cover materials, overheads, labour (as if you had to pay someone else to make it) AND your profit margin. Don't forget, nobody knows you are new at this but you.. people will stumble across your shop in whatever way they do, and as long as they love your stuff and your pricing is within reason, there's no reason why they won't buy it. Price them in a way that is creating a good viable business for you!
Now, don't let that description editing get too far behind... you'll live to regret it! :) Good luck!!
