I love my room at my parents house...I did it when we first moved in about 12 years ago--the walls are a teal/turquoise green, and we ragged over them with white, and it perfectly matches my bedspread (although, that is currently on my bed in my apartment so I have a makeshift pink, extra bedspread when I'm here. And I just have so much decoration all over my room walls/ceilings. I haven't lived at home for about 5 years, and I still don't want my parents to paint it white and open it up as another guest room or office. It pains me to think of it. haha. When it's clean (hopefully later today) I'll take a picture of it and post it.
I can't really paint the walls in my apartment, so my room there is pretty dull...but I am looking at getting all new bedding and stuff when I graduate in May (because I'm possibly relocating 1400 miles away and I have an excuse to buy new things there instead of moving everything). I still won't be able to paint walls, but whatever.
