If you raise the price, you will not be happy about it. Thinking its too high which may deter sales. And if you don't up the prices which folks thought you should, you second guess yourself. That's not a good place to bet at. I feel your pain.
Only you know how much time you spent on each items. How much you want to pay yourself. I am not saying anything about cost because we all, jewelry artisan know cost of our supplies. Some artisans think, this only cost $1, so I just price it... say $3. Folks are not only paying for supplies they are paying for our passion, vision, creativity... all those abstract things which are priceless :-). Think bringing value. Bringing beauty into their lives. Fashion. Style.
Etsy and PayPal will take their cuts too.
So you are the best judge. Don't go pulling out your hair if I say some of your bracelets seem a bit low to me :-)
