Rearranging & Redecorating

I am tired of the way things are in 2 of the main rooms in our house. I HATE the back room in our house. It is longgggg and very hard to divide. It never feels finished. I am going to try some suggestions from The Nesting Place to spiff thing up a bit. There are some wonderful ideas there. If anyone has any ideas for this monster room let me know. Here we go.

I also have to mention that we rent. So, unless I want to repaint later that' not an option:(
