Hi Ms. paige,
I think you should charge more for your bracelets. Can you actually make money selling them for that price? Once you subtract the shipping, the supplies (including packaging), any equipment you may use, you're probably not making much. And if you divide it by the number of hours you work, you probably are making very little per hour. Think about the time you spend making them, taking pics, going to the post office, to buy supplies, answering emails, packaging things up, etc.
Even if you keep the price, but charge shipping on top of the $20. If it's just a hobby, you may be happy just to make your money back, but you're not going to make much profit. I like your bracelets and the quality appears to be very high. You can charge more. Remember, it's hard to raise your prices later on!
I was charging $25 for them but I decided to drop it $5 because I wanted to get the moving out faster, which worked. I sold nearly half of my stuff within the first week. When I start making different types of jewlery, and am able to do custom work, I'll make more profit, but right now I'm just trying to make a little bit of profit so that I can buy more molds and other supplies to get started on the other ideas I have.
