Finding a way to cover an odd shaped window can be a challenge for any home decorator. Make this process easier by ordering custom window blinds. The variety of choices can allow you to coordinate the look in any room and create an inviting atmosphere where you can comfortably entertain family and friends. When working with a company to order your custom window blinds, they will often send someone to your home to obtain the proper measurements. If you are asked to measure your windows, take measurements for width and length from one side to the other. Include the window frame in your measurement for an outside mount which means you want them covered by the blinds. If you are measuring an odd shaped window, such as a semi-circle or triangle, ask for any special directions that you should follow. While installing horizontal blinds are not very difficult, request directions for installing blinds over an odd shaped window if you are doing it yourself.
