@chai2,
Heh. It's definitely not for everyone, and by the way I do completely agree with ehBeth re: resale/ renting. Keeping things nice and neutral is the way to go there, and those wallpapers are not nice and neutral.
The embossed wallpapers she posted could definitely work, though.
I was just kind of riffing on wallpaper in general. We plan to stay here a good long time (knock on wood), and while I haven't found any wallpaper I'd actually use, yet (for reasons of either style or cost), but I've enjoyed looking around a bit.
