It's for a big bay window but curtains won't be full length, just down to the sill as the curtain track is recessed above the window sill.
Carpet and rug are in the photo as seen. Sofas are brown leather, walls are cream.
I do prefer the plainer more orange one myself, if has a nice texture to it which you can't see on the photo. But I'm just wondering if it might be too much of a dark block of colour? The other curtains would probably be the safer, more neutral option.
The plain ones are £70 cheaper but I guess in the grand scheme of things if we have the curtains for years and years the price difference doesn't really matter.
