What should I get my Girl as a moving in gift?

We are finally moving in together (got the appartment on x-mas day, yay!) Since most of our money the first months go to paying the rent for the new place and my old room for a month, I am a bit strapped for cash, but I would really like to give her a gift that would mean something special for her, as to signify the start of our life together…. Anyone have a good suggestion ?
