We hung these over my daughter's 9 foot span of windows in her bedroom. They let in the sunlight because they are thin, great for her, bad for someone who likes to sleep in without sun. It makes her room look like she has a feature wall even though it isn't. Inexpensive mural, expensive window coverings. Only took the cat one time to try to climb the tree before it ripped a small hole in the curtain... oops. Not animal friendly.
