Christy Ferer recommends you accessorize indoors with antique awnings, terra-cotta urns, pottery, and gazing balls.
Rules to break:
"Garden furniture is for the garden."
Adirondack chairs, sandstone benches, chaise longues, and weathered teak or wrought-iron chairs can easily be softened and refined for the indoors with overstuffed cushions and velvet throws. Old, weathered pieces with peeling paint bring beautiful patina and texture to a room.
"Garden style is for causal rooms."
Bringing the outdoors in doesn't mean transforming your home into a greenhouse. Small "green" touches relax traditional, formal, and even the sleekest modern rooms. Put an old tool set on the small side table or a bowl of pebbles on the mantel. She suggests using a vintage urn as a planter. Old stone columns can come inside to define an interior entrance.
