I bought these panels for a sunroom. They are light filtering, which works well in the room. I gave this 4 stars, only because, the rod opening, of the panel is too tight for my 1" rod. So, I had to take out the seam, in order to be able to easily slide the curtains along the rod. I have added a pic of the top of the panel on the rod, after the middle seam was removed, to enlarge the rod opening.
