If you are looking for modern bay window treatments you have plenty of choices to choose from. Contemporary window treatments for large windows have definitely changed over the years, with many styles going quite upscale. It is just a matter of viewing all of your different options and then narrowing down your choices to what works best in your home on your specific type of bay window.
One option that is very popular is an automated system that can be raised or lowered with a remote control. This type of window covering system can be installed on all different sizes of bay windows, from small windows tucked in a corner to a full floor to ceiling version that covers a large portion of your wall. Available in a wide variety of colors as well as with different levels of opaqueness, these automated shades are very popular, especially with men. They can never seem to get enough of the fact that they can alter their blinds simply by using their handy remote control.
If automated shades are not the look you are going for, you can always consider installing a decorative valence at the top of your bay window over sheer curtains underneath. With a decorative valence as your show stopper the sheers fade into the background and your topper becomes the focal point. You can opt for a nice thick brocade valence or even a floral pattern. It just depends what sort of upholstery you already have in your room as well as what artwork is in place. It will often come down to deciding exactly what are of your room you want to be a focal point and what areas you want to fade into the background.
By thoroughly checking out all of the recent changes in the window treatments industry, you are in a much better position to choose contemporary treatments for your windows. You can still opt for tried and true styles if those are what suit your needs and your style aesthetic, but by exposing yourself to all of the available options you can feel much more enlightened about your eventual decision. The options are many; check them all out and then have fun choosing.
