I am not sure I would ever use wallpaper. I love it, and am drawn to it, but I am too much of a commitment-phobe. All that work, all that pattern - what if you change your mind? However, photos like this make me want to grow up and settle down with a nice, happy wallpaper. Smile at it over the morning paper and congratulate myself on having made such a good choice; gaze at it by candlelight and fall in love all over again. With the white floors, natural light, and red cabinet - could you really ever be sad in this room? I didn't think so.
Although... hmmm, pretty sure my husband won't like that one. That's the problem - even when you finally find the right wallpaper and are ready to commit, you realize that the other half has to agree, which almost never happens. (Very much like finding baby names BTW...)
