Last year, I was ready to pull out the paper, paint it black & make these for the windows. Why? Because I like to torture myself.
But then I was shopping at Michael's & WOW. I had a tear in my eye. Martha did the work for me. She has vinyl window clings of black silhouettes. Love her. She saved me much grief and pain. Today, I've tried to find them online & they've disappeared (all except the owl), but they are at your Michael's store. I saw them yesterday. (At least, they are at my store.) And they are reusable.
You just unroll it from the tube & slap it on the window. We have the black cat & moon, the witch and the skeleton. They look fun during the daytime.
And at night they show up even better. Hard to take a picture in the dark.
