I have a small room with 7 windows around (2 on the side and 5 across the front). I needed to cover the windows in a way that did not make the room appear smaller. I did try to install them myself, but I did not like my install, so I had it done professionally. The shades changed the room from an ordinary room to one that is invitiing and elegant. That is hard to do in a park model home that is situated in an RV park. I love the shades for my little get-a-way home. I will consider them anytime I am changing window treatments for any home in the future.
