I was talking to a fellow Etsy seller about this, and she told me something I realized I already knew: we know in our hearts what our creation is worth, both in street value and to our intregity as an artist and crafter. Don't undervalue yourself or you work, and don't be swayed by anyone who tells you that you are charging too much. Another piece of advice that I got from a local artisian years ago was, if you underprice, you are just as apt to not sell the item. She was in that position, and upped her prices a significant amount, and immediately her sales skyrocketed. "Immediately" and "skyrocketed" may only be applicable to art fairs, where we were selling, not Etsy, but you get the idea.
That's my story, and I'm sticking to it:) The recent conversation I referred to gives me reassurance, and I am not dropping my prices.
