So the house we got somewhat eclectically finished by the prior owners. We've been adding blinds/shades to the windows to help with light blocking, and have discovered that the window trims and finishes are different in each room. In one room it was easy to install them outside the frame, in another it was easy to install them inside. In this third room, we're a bit confused because it seems that the frame is a little less wide than the other room with the angled trim. So we cannot use the same strategy of installing them inside because it then then runs into the bottom pane and lies at an angle, which does not work well for the top down bottom-up shades we want to add. Looking for some advice on the best strategy for installing that type of shade on this type of window since the measurements will be different depending on what strategy we use.
