So far we live our new blinds. Don’t be afraid to follow sizing instructions we leaned on the side of caution and probably have about 34 - 1 inch of space total that we could fill up. Was pretty easy. We have recently merged homes and are in the process of small renovations. We plan to also have light curtains. Will try to share update after using for a few months. We have been using for a few weeks now. Can you find the they do help to keep the heat out of the room. They are not room so if you’re looking for that, make sure to purchase that option. We weren’t necessarily looking for that and knew we could get room darkening curtains if anything.
