I ordered the mushroom colored curtains, and they do a fantastic job of blocking the light from my huge window while looking decent to boot. I used to wake up several times in the mornings as the sun rose, but now I could sleep in all day if I wanted. Also, they have held up under several weeks of furious attack by two playful kitties as they run around on the windowsill. 

If you're looking for curtains that look nice and block out a lot of light, these are the ones to choose.
