Well as far as furniture goes, you’ll need a dresser (unless you just use a closet) and I like nightstands! That way I can put my phone and DS and books right next to me, and a lamp. Let’s see, maybe a desk? I enjoy having a desk! You could make your own accessories. Get picture frames and paint them to match your room, etc. Get a long-lengthened mirror, hang it on your door. You could also get things likes a white erase board or bulletin board and put pictures on it! That’s always cute.
