These curtains are absolutely amazing and absolutely beautiful!  I didn't think they would blackout the light that much, especially being a light color, but while it doesn't blackout completely, it works extremely well, and you need to close your eyes when you open the curtains or it will hurt your eyes when you see how much light comes through!  They really do a super job!  They are very classy and do not look cheap at all.  The thickness is wonderful and the quality is great.  I sent a picture to my mom who wanted a set herself, so I sent her some and she loves hers as well!  It really is a great product and it certainly does its job very well!
