I think i would do a nice piece of art instead , I like guest rooms to be kind of gender neutral like a high end hotelI think I would choose a bit more interesting bedding , choose a wall color to go with it some nice lamps proper sized and forget the wallpaper. If you like green do a soft grayed green for the walls if it works with the bedding.BTW keep the dogs out of the guest room

Cute pup.

Just a thought: Agree w/Patricia. If that cute pooch is left in the guest room to make its own choices, that bed will be a pet bed rather than a guest bed.

Not a fan of wallpaper; real chore to change later. Would probably repaint … then you could consider adding 4" wallpaper TRIM tape at the top of the wall next to the ceiling to help create the theme/color scheme you want for the room.

Wallpaper rarely lends itself to art in a complimentary way.

If you have already decided on wallpaper, I like the third one for its two-color options; second, I'd pick the second, less bold colored one. The only way I'd want the first "busy" one would be if it were only going to be on one short accent wall and the rest of the room painted in a pale version of the same green.

I like the grass you were looking at earlier, but for a full wall, the first two papers are nicer. I am a fan of green, too, so I might be biased. :)

The first one is very bold of course, and the second is more grown up and I suppose more sensible. So yeah, the middle one--but how large is the pattern?

I'm not sure what the order of picking these things out should be, but i'm sure paper samples figure into it somewhere.
