We are going with a combination of window coverings in our house.
Home theatre at the front of the house (only windows on the ground floor) they will be two plantation shutters.
On all of the other windows it will be roller blinds. In the main bedroom we will have roller blinds and curtains - only because DH works night shift and we need the bedroom as dark as we can get it.
We are also going day / night roller blinds, they look very classy and certainly aren't cheap looking like some verticals can. Also having shutters in front of house and bedroom. Curtains are definitely not old fashioned, in fact I think they look fab especially sheers in blacks, greys, brown BUT if you have cats and dogs you may regret them. I will need to replace the 'cheap' sheers in our rental because cat has taken a shine to them.
