You don't have to live retro or mid-century or in an industrial loft to go in circles...garden, classic contemporary, cottage,traditional...all will get a lift from the fresh geometric of circles...don't think circles are just for contemporary retro- chic tastes...circles mix in anywhere...
Start slow-toss a pillow like this one from Koo de Kir or place an accent lamp like this Madison Lamp from Williams Sonoma Home one from next to a reading chair or bedside
(Horchow)
I love this "Twiggy" chandelier from Horchow in a breakfast room or kitchen for a taste of circles but it would work in an entry hall or high stairway too
Speaking of chairs, these are favorites and are at home by a Chippendale armoire or a glass desk...love this Frances Elkins chair from Downtown20 pulled up to a writing desk, as an accent dining chair or in a bedroom
and this chair is coming home with me! From McGuire Furniture it is the ideal corner chair ,even by the most traditional fireplace, and I love it in a study or garden room and of course pulled up in the dining room. A simple cushion and it works in any space.
and this Daybed from West Elm will be fabulous in a study or guest bedroom
Maybe you have a large space or high ceiling and you want to warm the room or ground the space but still maintain openness...circles work for that like in this rug from West Elm
If you still are not sold that circles will work for you think garden! yes, garden! Circles are often incorporated in garden design. This perfect Elsie pattern(yes after Elsie de Wolfe)dinnerware from Charlotte Moss takes a classic trellis look
like this one from Walpole Woodworkers
and these wonderful garden maze prints I love in a sun room or breakfast room
I adore this coffee table from Z Gallerie reminiscent of a perfect garden seat...LOVE!
and if you still just only want to put a toe in the circular pool...go for this sweet "Molly"dotted look for the bedroom from Neiman's
