Step 1 Decide between Inside or Outside Mount
First, you’ll need to decide whether you want inside mount or outside mount blinds. Inside mount blinds, as the name suggests, mount inside your window frame, while outside mount blinds mount outside or over the window frame. If the depth of your window is shallow, you may need to use outside mount blinds as there may not be room to mount them inside. Inside mount blinds will give you the cleanest look overall, while outside mount blinds offer more variety, as the window frame size doesn’t matter when choosing them.
