Christina Hendricks says she's not sure if she's ready to film the final scenes
of her hit series Mad Men
, but she's also enjoying spending quality time with her husband as she gets a month-long mini-break from the set.
, 38, joined other celebs including Jaime King
and Ellen Pompeo
at a design party in Los Angeles Thursday for online retailer One King's Lane, which launched its new vintage decor line Hunters Alley.
"It's scary. But we had a really good run," Hendricks, who plays flame-haired
and sexy office manager Joan Holloway, told PEOPLE as the clock ticks on shooting Mad Men
's final seven shows. "You want to quit when you're still on top. I think [series creator] Matt [Weiner] is ready to move on. It's going to be hard … I don't feel ready."
But as the show is nearly over, one happy constant in her life is her marriage to actor Geoffrey Arend. The couple
, wed since 2009, get to spend a fair amount of time together and may be taking their life bi-coastal as he's currently shooting a pilot for a N.Y.C.-based series. She'll happily tag along if everything works out.
"We've been really lucky. We are mostly always in the same city," she says of their work-life
juggle as actors. "When one of us isn't, we travel together as much as we can. We have a two week rule. We try not to be away from each other no longer than two weeks."
, who got her decor fix on, said she's currently collecting Majolica and hopes to put her latest purchase – a colorful lobster platter – on her kitchen wall.
Home time with her hubby is precious and her idea of a perfect date-night with him is low-key, Hendricks shared.
"Probably go to a beautiful cocktail bar with beautiful ambience," she tells PEOPLE. "Go have dinner at a new amazing restaurant. Then go home, watch a movie and snuggle up with my husband."
