NEW YORK – Nothing punctuates a room like a gorgeous decorative object. From a 17th-century stool to a midcentury decorative sculpture, a special piece can instantly change a mood and elevate the décor. Selecting from property in our Designer Showhouse and Auction, some fashionable New York friends chose their favourite items, styled the pieces in their personal environments then shared images on Instagram.
