So you're running two threads on this space? I think you'll be happier with the responses if you stick to one thread for the entire makeover, as it is all inter-dependent - foyer - living - dining. Now that I know that the living dining are together I'd suggest you use measurements from the blocked space above the windows to determine stripe width in the dining space if you go with the wide horizontal stripes I suggested. The pattern is already set for you if you take the measurements. You could also make the stripes the width of your lower window section, or half of it, but use the horizontal lines already in your space to determine the other stripes you may add.

No such thing as wallpaper for floors, but there are a few good solutions for water resistant flooring. Pvc, vinyl, linoleum, epoxy or polyurethane paint, for example. I see you live in India, I have no idea what products can be bought there.

well i do trust him....but I m just concerned about the wallpapers....haven't really used them nor have seen anyone with that in the locality.....that's all....
