oh my they are lovely leave it exposed or maybe at night you could place a decorative dressing curtain in front of it

Gallery Glass found at your local craft store. Goes on white, dries clear. Apply with fingers! I love the product. I did 11 windows in my home ! Very budget friendly. Best of luck.

Pin or attach fabric (Net) and scrunch up in the middle with elastic and or ribbon................Or you could use a Cling to obstruct direct view. or Beads on strings..

Here are tons of ideas. I like the two above me, though!!
