Coolest blinds ever!

Cordless window blinds are the coolest thing ever invented!  I showed them to my husband last week and he was fascinated.  We bought one for every upstairs window we have.  :)  They're so easy and the light blockage is incredible.  The white ones softens the light let in while keeping the room bright in the daytime, and the dark one keeps the den pitch black, even in broad daylight.
