It is hard to find tiers that are longer than 36".  I bought these in the 45" length to put over the window in my back door.  The afternoon sun had come in at a blinding angle.  These curtains have taken care of that.  They are light filtering but they are opaque enough to keep the direct sun out and to offer privacy. I may need to turn the hem up to make them a better length but I am just so happy to find tiers that were long enough since the 36" tiers I had before were too short to cover all of the window.
