Yes, you can, but there are things you need to keep in mind.  Clearance – Ensure that the way is clear when you want to open your window, to prevent damage or obstruction. This means you need to fully retract most blinds/curtains to make space.  Mounting Location – By placing the blinds/curtains in a place that doesn’t obstruct with the reversible function, you can forgo the hassle of clearance. The location you place them can be in many areas depending on your house, but if no suitable location is present, you can build one. For example, you can build ceiling mounted tracks.  Frame-Bound Blinds – Some special blinds work well with reversible windows. For example, blinds that fit directly onto the frame of your window rather than outside of it. These will move with the windows when opened, so you will not have to worry about clearance.  Cord Length – For blinds with cords, you must be careful not to allow the cord to get tangled up in the window.
