Make a throw pillow out of the extra fabric. Or pillow cases for your bed.

What really helped in our little windowless bathroom was to add a mirror that looked like a window - it helped bounce the light around a lot!

What about a large piece of art?

you could take an old window and add photos to it or just leave it glass and add the curtain on it- or repurpose it in another area of your home

You can definitely make a fake window on the wall.

Our spare bathroom has no windows buy a solar tube made it so bright during the day people look for a way to turn the light off.

Make covers for tank lid, toilet seat, kleenex box.

You could definitely create a fake window. A mirror might be a great idea since it will reflect the light.

Sew it into a large pillow case shape with a top drawstring, and use it a laundry bag for bathroom towels.

I like the idea of adding a mirror window. Hobby Lobby has some mirrors that would work for this! You could also go to IKEA and get a doll bar and hang some faux plants under it.

Definitely create fake window, with a shelf for shampoo etc or decor

I would get an old window frame, but a mirror behind it and then mount a curtain rod above it, as you would with a traditional window and add the curtains of your choice. It would look darling.

I agree with Kim! An old window frame with a mirror would be cute and a fun decor piece
