Beautiful color and design! Definitely an accent in my neutral based room! I love it! If you are looking for a curtain that completely blacks-out the light this is close to par.  It allows some light but not enough to disrupt the room of glare into your eyes.  It is very well filtered and block about 90-95% of the light.  For more of a blackout affect I suggest adding an extra panel or two.  I have a 70x70" window on the south-facing side of my house that receives a lot of light throughout the day I have 4 panels (2 packs) and it provides the perfect amount of coverage
