I bought it at a garage sale for $4 and painted it black. It's made of molded plastic. It originally hung over my vintage mantle when I was doing a black and white damask theme in my bedroom. Now I have a new plan for it. I'm going to paint it a bright cheerful color and hang it in my living room. Here are some pictures that inspired me:

1. Dottie Angel
2. Caitlin Wilson's home tour on MadebyGirl
3. Etsy seller apartmentjeanie
4. Apartment Therapy

What do you think? I'm leaning towards yellow or bright blue or maybe grass green.
