I think wallpaper is small doses like in a foyer is BEAUTIFUL.
I love vertical stripes. They just take my eye up the stairs and make me want to go and see what else is up there. I also LOVE the contrasting black and white tile and the contrasting stairs. ooo...soo pretty.
Glass Furniture is also great for a foyer because it doesn't take up visual space but accomplishes a purpose.
I also love seating in a foyer. And I love the pop of color with this pink couch. I think foyers are a great area to do something spectacular that would be overboard in any other room. Like this pink couch! In another room the pink might be strange and odd. But here it is perfectly placed.
