Hello, I have a 16 foot long entry hallway. There are closet doors and a bathroom off to one side and just a blank wall on the other. I am all over the place with how to decorate it: wall mural, Lego wall, some sort of LED thing, pop art gallery wall, etc. Hanging art is the easiest solution but there is art all over the rest of the house so I want to do something different here. Also it's a rental so I can't do anything too permanent. Any and all suggestions would be greatly appreciated. Thanks!
