The only curtain we bother with is the one on the back door.
Since we like most have a screen door also,I moved the "curtain" onto the screen door.
I used the original rod and mover the brackets onto the screen frame.Than used a piece of dowel for the bottom,and just roll it up when not in use.
The curtain on the door between it and the screen is WORTHLESS,you can't raise or lower it without opening the main door.
