But...installing it the way it is suppose to be done was not going to work on my window. The window frame is not deep enough to accomodate the width of the bracket nor the width of the top of the bamboo shade. So I pulled out the cords and simply nailed the shade right to the window frame using 2 1/2 inch wood nails!
It's up, it's centered, no cords to pull so no undo stress on the nails...it is secure for the pupose it is intended.
And I think the shade looks really cool plus it provides plenty of privacy for my first floor powder room!!
Cost of the shade...$22.00 + tax
