"I just wanted to do something chill," explains Moss (who is on Hillwood's International Council). Of course, "chill," for Marjorie (and for Charlotte), is no paper-plate picnic. And that's all part of Moss's message: "Anyone who entertains, entertains anywhere, anytime, anyhow," she says. "And the message is no matter how nice the things you have are, the important thing is to use them." And use them Moss does, in this setting, which places Post's export China atop table linens, sourced by Moss, at a wooden patio table she found at a small shop in Connecticut. "I tried to channel Marjorie in every step," Moss says. "Even the rustic chairs, I topped with silk covers for that balance." To give the whole scene a firm sense of place, Moss looked to one of Post's other estates, Camp Topridge in the Adirondacks. Moss used an oversize image of the camp's cabin as a backdrop for her table and covered the whole thing in a canvas tent. But of course, even the most rustic gathering is incomplete without florals—Moss's are courtesy of Louis Miller in New York (faux, to last the exhibition's four-month run).
