On my french doors that receive alot of traffic, I have Roman shades. They are weighted and have withstood traffic better than anything else I've tried. Plus they are great for privacy. They do darken the room more than I'd like, but I can't figure out anything else that works as well for what I need it to do. AND, they don't make the doors so heavy to open.
Yes.. I like those, very much. My friend Pat has some new thing that I love on her enclosed Lanai too. Will also check those out. They pull up and down and not to light darkening.
We are spending Thanksgiving at her house like last year.
I have sheers and draperies on "swing arm" rods on my french doors. I used two sets of rods on each side... Can have a totally open look in the daytime or during times when there is lots of traffic or just the sheers when I want to filter the light or swing the draperies around when I want privacy. I wrestled and wrangled with them and lots of sketches before I got what I needed.
