This is so homey! I, too have a quilt shower curtain. Maybe I'll make another just like this to switch the decor. (my walls are a creamy white.)I used a metal clothes rod (for closets) for my curtain rod. DH wanted to be sure it wouldn't fall down--so rod ends were screwed into the studs. I sewed tabs to the top to attach to curtain rings.
Here's mine.
