The Black Eyed Peas' current ode to wainscoting? In entrance halls:
My mother installed chair railing in two-thirds of our Craftsman-style house in the early 1990s: never my favorite look (the dining room had brick red paint below, pineapple printed wallpaper above) but it was sort of mitigated by the picture molding about 14 inches from the ceiling. Lots of horizontal lines ... very Prairie School meets Little House on the Prairie. We won't discuss the painting of a bald eagle on black velvet that my dad refuses to take down, a gas station gag gift gone horribly wrong.
But each of the beautiful examples above, snatched via Miles, Remodelista (that's ex-Dominoer Dara Caponigro's dining room) and G.P. Schafer, has real deal wainscoting -- chair rail + paneling underneath -- a look I much prefer.
So I'm fully against solo chair rail and 100% 50-50 on wallpaper or fabric above wainscoting. These rooms have a certain chic and I know it's all in the application, but I need hard and fast rules on the topic. Does it get too busy? Too broken up? Fergie Ferg, I know you hear me.
