Trendy Wallpaper

my wife wants to rip it down because she thinks it is "old" research

No, not totally. Grandma's Farm. Old, old, old.

keep ducks to the basement or den or office Flag

Absolutely not - wallpaper borders are definitely OUT! Sorry but the guy is quite bourgeois here, it's time for a renovation.

NO! It is not connected: fashion. Rip it down and do a little ledge instead if you need a border up there. Paint the walls first! Use something cool texture to your walls while you paint.

One would look old. Something like this is a personal taste. If you're ready to sell your house, I'd take it down.

Listen to your wife. I agree with others who have written that the border makes it a dated look.

in the dining room? I do not think so, maybe in a little girls' room.
