Arched window shades ideas can also be applied with the curtains as well. The shades and the curtains can be implemented onto the same window. The concept is to make the window look unique and at the same time window can have both the options. According to the size of the window the shades are used and in between the spaces of the windows there is the rod used to hang the curtains. The curtains may not be used to cover the windows but these curtains can fill the gaps between the windows. This combination is frequently used in arched window shades ideas.
