Decorative frosting films are a practical option when you need privacy but do not wish to block the light with curtains or blinds.
I like this collection by Brume of natural foliage, kitchen and laundry themes, bathroom doors, letters and numbers. Kiss the Cook and the utensils look great over the sink window.
UK-based, Brume produces any of their design pre-cut to your exact specifications, so you can apply them as soon as they arrive with no mess or fuss. You specify if the film will be installed inside or outside your home. I think that they ship outside United Kingdom but I could find it for sure.
+ Brume – price varies per dimension and if for indoor and outdoor usage
