Sometimes elevating a dining room’s look “is as simple as a beautiful mural or wallpaper that sets the tone,” notes Kristin Peake, principal of Kristin Peake Interiors. She clad the walls of a dining room in Northwest DC’s Spring Valley neighborhood in a delicate custom mural that imparts airiness and light via a botanical motif; blue-velvet host chairs pick up the hue of the grass-cloth walls in the hallway leading to the space.
