I think you could afford to raise your prices. Like everyone else said, your frames are beautiful and you definitely don't want to sell yourself short. I started listing things this past November and it was really hard for me to raise my prices but I realized that if I wanted to put money back into my business, I HAD to raise them. Locally (I live in a very small rural town), there is NO WAY I could charge these prices, but on Etsy, you have such a wide audience! People shopping on Etsy understand that handmade tends to be more expensive. Personally, if someone does a search for my items and they're on the low end, I worry that they might think "cheap" even though they're not. Good luck to you!
