Tell ya what, I agree not to put any wall coverings up on any house I sell to you. Good enough?
(Not wild about wallpaper -- I prefer stencil work, given a choice -- but I'm not offended by it either. Sometimes it can provide a nice effect that would be hard/expensive to get any other way, eg the large photomurals. And I haven't let even textured wallpaper keep me from simply repainting a room...)
