Selling my ceramics in person is awesome. Selling ceramics online... Not so great.
In person, people get to touch things. Pottery is very much about how things feel, and that can't be expressed online.
I haven't sold anything on Etsy in months. I made a month's rent in one afternoon at this recent craft fair.
When I ship ceramics, despite my best attempts to package things for Armageddon, it's inevitable that every so often, things get broken. Neither USPS or UPS has ever paid for the damages. In person, I wrap the pottery in newspaper and people carefully carry them home.
Finally, as much as it's nice to hear some feedback over the internet, there's nothing more satisfying than seeing how happy a customer is face to face.
