"You want to quit while you're still on top," the actress says as her series comes to end

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.

Hendricks, 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.”

Hendricks, 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.”
