Located in a small workshop around the corner from Campo dei Fiori, Marina handpaints porcelain cups, bowls, saucers, vases, and more. Her designs range from classic and elegant to fun and whimsical. And the prices—starting at about €15 euros for a small saucer or ashtray—aren't bad.
But I'll let the pictures do the talking.
Picta Porcellane is open from Monday to Saturday, from 10am to 7:30pm. It's located at Via dei Cappellari 11, right off Campo dei Fiori.
