This is pretty much my living space, aside from my studio space which is off to the right. I recently acquired a couch, which I put at the foot of my bed, and incorporated a sort of sitting/reading space within my sleeping space...
On my table I stacked some books, and added: an old camera, vintage French chalk, old matchbooks, wooden colored pencils, and an interesting beer coaster- along with some beautiful fresh flowers (always a favorite to have in my room).
I've also been collecting glass jars and clustering them in various places around my room. Make a one-time investment of $4 in 100 tea light candles from Ikea (here), and you can make a really soft, beautiful, ambient display when you place one in each jar.
As always, I hope you're inspired to try some of these ideas yourself in your own space!
