These window panels exceeded my expectations.  Not only did I get something that helps filter out just the right amount of light but I got curtain panels that I can change out in three different designs. 

I have fairly tall windows and these fit perfectly both legth and width. 

They are easy to hang and pretty easy to wash. Instructions for wash are on the label at bottom of curtain. 

The window panels include the hanger rings, which are already attached to the panels. So no extra work.
