We had Hillarys' white painted basswood plantation shutters fitted to our bedroom and cloakroom windows a few of years back. We too have nice champagne coloured silk 'dress' drapes on two sets of French windows, though. I absolutely adore the shutters and the lovely way they filter the sunlight when open, and keep the room almost totally dark when closed.
We have cottage style dormer windows in some of our bedrooms. Finding something that fitted snugly into the dormer and kept the light out but didn't flap noisily in the breeze (as both curtains and roller blinds did) was necessary because, until I retired, I was a shift worker and often needed to sleep during the day after night shifts. These shutters were ideal.
It is much less work wiping shutters clean than taking down curtains, removing hooks and washing and ironing the curtains. The effect of pure white shutters against coloured walls is lovely. Also, when you just want to pop into the bedroom during the day to change your clothes, you don't have to draw the curtains and cause the neighbours to wonder what you're up to! A simple tilt of a rod gives you privacy. You can also look out without being visible to passers by. If ever I move, I shall have these shutters installed again.
