Practical- and good looking- idea

I had this when I was living in Berlin. My room, in the flat I was sharing with three other people, was nice, but a little bare. One day, I had the brilliant idea to hammer two nails in the walls, running the length of the wall, and to attach a string to them, on which I would hang all the wonderful cards and other knick-knacks I picked up around the city. It gave my room a wonderful look, and reminded me everyday of the things I liked.
Yesterday, I decided to do the same here, in my little buro, and it took no time at all for the strings to be filled with things!
It looks great!
