I purchased these liners for my son's bedroom to place behind an already purchased set of curtains.  The design of these panels provides flexibility for any curtain hanging style - ring, pole, grommet etc - which makes them a great alternative to having to buy a whole new curtain, sew in a blackout liner to an existing curtain, or adding a double rod.  What a great find!

Pros: Versatile, Excellent Quality, Great Value
