Looking to tap into your knowledge please. Our upstairs spare bedroom has three walls of glass. It makes it hot in summer & cold in winter. The previous owners installed green (!) vertical blinds on two windows (the one to the right of the bed is a sliding door onto a deck) and one lot of curtains. We intend to paint the walls white so ignore the green paint (!). We are looking to change the window treatments but don't want it to look like a padded room eg three sets of curtains would probably look a bit weird. The window behind the bed head looks onto our culdesac. Any suggestions on combinations? Thanks!
