Much as I love wood blinds, in your case I would go with the white. I'm afraid the wood blinds would chop up this expanse of windows where as the white would give you a blank slate. You could always add color in roman shades, etc. (Love the flowering trees!)

I would love the rocking chair too, but way too expensive for me, unfortunately!! Yellow could be good... hmmm, will have a look, thanks

also have uploaded a photo of our piano and mirror which I love. and I photo of our dining room light which I would also like to keep there.

Certainly dual rollers have a more contemporary look, especially when they are used with a sleek fascia. Dual rollers offer huge versatility in light control and have minimal upkeep (read- no dusting required :-) ). The big thing that is going to determine what you do is the amount of depth in your window as dual rollers require a fair amount of depth. I've attached a photo to give you a sense of depth though the requirements certainly vary with manufacturers .
