This gorgeous photo was sent to my inbox by Mitchell Gold+Bob Williams.  How beautiful is the pure white, shadowed in bluish gray to match the subtle stripe in the rug.  The arrangement of the accessories are so important here, since the scheme is completely monotone. 

To achieve this look, imagine an invisible triangle when accessorizing.  This will avoid static, boring groupings and will prevent a vignette from developing into a pile of clutter.  If there are too many items to arrange this way, there are probably too many!
