When Krysten Ritter isn’t kicking ass as Jessica Jones, writing gripping psychological thrillers, and hanging with her canine pal, Mikey, she knits—a lot. (Want proof? Just search the hashtag #krystenknitter.) The raven-haired actress loves knitting so much that she joined forces with DIY knitting brand We Are Knitters on a new capsule collection, which just dropped. The lineup includes eight different knitting kits designed by Ritter—her top pick, she told us, is a tricolor cropped sweater designed specifically with her bestie and stylist, Ilaria Urbinati, in mind. (It can be yours for $99.) While Ritter said she technically owes her knitting expertise to her grandmother, her love for the craft didn’t explode until she was on set for Mona Lisa Smile with fellow actress and knitting aficionado Julia Roberts, who kept a big bag of yarn and needles by her side throughout the filming process. “[Julia] got the whole cast of women super into it,” Ritter said. “You would just see everyone knitting. It was really cool and I got very into it after that.” (Imagining Roberts, Ritter, Maggie Gyllenhaal, Julia Stiles, Kirsten Dunst, and Ginnifer Goodwin hanging out and knitting together in ‘50s-style garb gives us all the feels.) Her favorite part about her beloved hobby? The fact that she can do it anywhere—knitting in public, especially on the train, is particularly fun for her—and anytime, like on set for Jessica Jones. “The crew always gets a kick out of seeing me knitting when I’m in full Jessica Jones costume,” she said. Below, we caught up with the actress, who’s currently touring her new novel, Bonfire, to talk the We Are Knitters collab, the soothing powers of stitching, and the “secret nod” all public knitters share.
