I like the first, but you may want to consider the repeat pattern of both papers. You have a large space and your cost will be substantilly higher with the first choice.
Since the TV wall future arrangement seems contemporary, I like the way the wallpaper #2 looks. Is the rest of your furniture contemporary as well? Tape the sample wallpaper on the wall for a few days and live with it.
A similar paper is in photo #1.
Photo # 2 has an interesting idea: they combined wallpaper with mirror.
plz advice what can be done to these long walls
Want suggestion to correct my rustic wall
Dampness on wall?? Which material I can use in interior wall..
plz suggest me best modifications for this plan
The second wallpaper looks best with the space. It will add a lot of character to the walls.
I love the wall paper mirror look !! I would pick the modern 2nd choice .
Maybe something like the mirrors can be done on the DR wall. I think it would be best to talk with a decorator, though.
