OK, I'm a day late again!
Although this window is over a tub, for once the intelligent choice was made to place the window higher so that you can't see into the master bath.
This design is so simple, deceptively so. It was rather simple to hang the curtain holdbacks we used for this throw swag. (I say "rather simple" because I didn't have to do it! My installer is 6'4" so he didn't even use a ladder!) Dressing the swag is the hard part.
