*nodnod* I think I'm going to negotiate for the futon in the separation, myself. With a foam topper it makes a comfy bed that can fit two if they're friendly, and the rest of the time I can keep it couched up and actually have access to my craft table. Multi-purpose rooms FTW!

Maybe a purple curtain? That should go next to the pink gracefully and match the undertone of the walls. And if it's diagonal from the chair, that would pull the space together nicely.
