Anchored by a neutral, custom-sized rug from Rugs As Art in subtle shades of gray, an off-white linen-blend sectional by Cassina is accented by custom made black and white pillows. A black and white throw drapes over the chaise. â€œI always like a little bit of black because it gives definition to the space,â€? says Geisdorf. Customized chairs wear pin-striping in a soft-textured fabric.
