I had blinds for another window years ago, easy. This time it has been a nightmare and impossible to manage solo. For this size, the lugs don’t hold the blind in place. Screws need to be introduced as you hold the blind in place and partially unwrap the blind to access screw hole. Impossible to manage with only 2 hands. Difficulty of pushing side rails in place can’t but help mark the bottom of the frame. None of the videos I watched indicate the difficulty experienced.
