I am often amazed when customers come to me and say that they have been told that you cannot have one blind for a wide window (in some cases not that wide). Having one blind on a wide window is stylish and gives impact. With the right construction and enough support, they work very well. With a chain mechanism with the correct "gearing" they are not difficult to operate. Over the years I have often gone over 3 metres, and the results have always been rewarding.
So if you have a wide window, or a tall window where you want a contemporary look of a roman blind, email email@example.com.
