In my closet at my parents house, I had sharpies and anyone that came in my room would sign the back wall of my closet! idea for guest room: Paint dresser all white and leave a sharpie for guests to "sign". kinda like my old duct tape idea.
Hanging lights with crocheted wire covers. Would be cool to to the covers in something like clothes line, hemp twine, plastic packing cord -- industrial materials. Also a cool way to just cover the cords that snake everywhere from lamps.
