I ordered the Eclipse liner panels for my daughter's room.  We ordered light blocking curtains from another store but her room was still bright as day with curtain closed.  I ordered these panels to put underneath and her room was much darker. She's only 4 months old,  so this has helped both of us get more sleep! Using the enclosed hooks was more hassle... so I just bought a second thin rod and put underneath the decorative curtain and it works great!
