The astronaut themed curtain replaced my 40 year old faded yucky curtains from a long gone era adding excitement to the room. The two curtains slipped through my curtain rod easily. These are not black out curtains and were never advertised as such but for you day sleepers out there, get some blackout liners and all your light problems are solved. I used some duct tape to keep the panels together when I run the fans to keep them in place but I might add snap buttons soon enough.
