Window Film
Not many dabble with this decor option, but window film is a temporary and creative way to bring some more color into the room. It's also a great way to add some privacy to your space, especially if you have large windows that would make window treatments too costly. Emily Henderson showed just how chic these adhesives could be when she chose mutli-hued ones to cover the panes in her studio.

Some great places to browse window film options are Stick Pretty, Scandinavian Design Center, Gila Films, and Emma Jeffs.
