However you want. I'm 13 years old, female. I recently moved to a new apartment. I have 4 cats, and just love them, so I "catified" my room. I put shelves up on my walls, and hung up litter mirrors for my cats. I then hung up pictures of them and my 3 little rats. It looks awesome.
Ya know what's really cool? My girlfriend has it and so do I.
Christmas lights. Just white christmas lights. You can turn off the lights in your room and just leave those on to make a really neato, calm and peaceful atmosphere :D
You can pick up rope lights or christmas lights just about anywhere for a few dollars.
I'm moving and want my room to be really cool. I'm a 15 year old girl. and will be doing it myself so nothing too hard, any ideas on color schemes and things for my walls? pictures would be very helpful.
