Hi, I am looking for window coverings for my lounge patio doors. There are 4 doors (in a recess approx 240cm x 207cm) which lead onto a street facing first floor balcony, so I need something that provides privacy. I have 50mm white wooden venetian blinds on all other windows, which I love. Does anyone have similar wooden venetian blinds on patio doors? Or are perfect fit blinds the way to go? Many thanks!
