Potomac Promenade, the Giant-anchored shopping center in Potomac Village, is finally bringing some new tenants to its long-dormant mini-mall. This week saw the openings of Kicks Karate and FiberArt Studio, joining the recently opened Kumon learning center as the mini-mall transforms into a family-friendly place where parents can drop off their kids while they pick up the groceries. “This used to be the mall that nobody goes to, but that’s changing now,” says fiber artist Anja Caldwell, who relocated her studio from Glen Echo Park. Caldwell will be teaching “everything grandma used to know,” from knitting and crocheting to sewing and felting. “This will be a happy place where we make hats, dolls, pillows, hair clips and jewelry,” she says. “I don’t allow glue or glitter. Everyone who leaves here will at least be able to sew on a button.”
