Here are some great alternatives for French door window treatments. You can go with a door panel curtain as one option. These curtains will lie almost flush with the door glass and you have endless options regarding fabric styles and designs. This is a great option if your French doors can be seen from a number of rooms in your home. Another excellent choice is honeycomb shades. The headrails of these shades aren't deep and they won't get in the way when you open and close the doors. There also won't be any trouble with the door handles either. French door shades also come in a variety to materials and colors.
Another popular French door window treatment is blinds. The great thing about some blind designs is that they retract completely into the headrail giving you even more light and view. You can choose from a number of different blind slate sizes depending on the look you want to create. With door window blinds just make sure they are securely attached at the bottom so that they don't bang against the door every time it is opened and closed. You can't go wrong with any of these choices. Just pick the one you like the best.
