Sorry I mean big window not bog window .

can you give me more explanation please ..
and what if the two beds are white so what colour should I choose for the curtain and the rug ?

Not a Pro.

Are you keeping the wall color and wallpaper? if you are, and you are doing two beds in white.......I would go white sheers with a white blind under it.

Start setting up the room and then post pictures of the room. People will chime in with decorating advice.

White beds and white bedding will allow for any color you want to add. Try something the kids like.

thank you very much .. I am confused between colours so any suggestion would help ..

If you are between colors, which ones are you choosing between? Can we see photos of the ones you're considering.

baby peach or baby blue

are you gutting everything out of that room, the wallpaper lights and flooring?

Is this a nursery? Are they born yet? Is it twins; one of each? I would keep the curtains white and dress the white beds in a neutral sage, mint or yellow to span the boy/girl issue.

Decon .. thank you very much .. No I have not children yet .. in the same time I can't use a white curtain . any suggestion instead of white ?

You dont have kids?

Sangy .. yes I do not have kids yet .. I just prepare it to be their room

Why can’t you use white curtains? Also, can you post a closeup picture of the wallpaper to get a better idea of the colors?

this is the wallpaper

Not a Pro.

If you have white curtains in your living room and you need a change, get curtains the same color as your wall color.
