To get this look, I ended up taking a store-bought window curtain panel (or 2) and made it work as a shower curtain. I want to show you how easily you can do this.
HOW TO CONVERT A WINDOW CURTAIN INTO A SHOWER CURTAIN
I was using a shower liner so the actual fabric would not get wet and ruined.
So I knew I had to line up my fabric panel with the grommet rings in the shower liner.
My shower curtain hangs on a curved rod, so the 5 or so inches that was left of the shower liner, I hung on the center of the curve for both panels. That way it is easily hidden.
If you have a straight curtain rod, you may need to pleat the liner by simply putting two of the grommet holes onto one of the shower hooks which will shorten the width.
