Inside or outside mount:
As the names suggest, a Roman shade can be installed inside the frame of the window and also on the outside. To install the shade inside, there should be enough room in the frame to accommodate the shade. Outside mount can be right above the window and on the ceiling when there is very little space between the ceiling and the window frame.
Roman shades come with their own two brackets for outside mount. Decide whether you want to install shades just above the window or on the ceiling. Lift up and hold the shade to the place you have selected to install it. check for length and width measurements.
Hold up the two brackets to the wall and mark the points where you will install the. Use a level to ensure that both the brackets are even with each other. Drill a pilot hole and then install the brackets suing the screws that came with them. Both brackets should be perfectly aligned with each other.
