Thanks, Kim (and others). I agree that the shelving is very problematic. I am not sure how much I can reduce it without getting into a lot of stress with my husband, so I will have to approach that carefully.
Greyscale, I have the Apartment Therapy book!
Thanks for the overlooked perspective on horizontal lines, Rambling Ann.
Laurinda, that primer on lighting has been real food for thought. The room is well lit from the recessed lighting, but it's not interesting light. I definitely could use some accents and task lighting. That would create a need for end tables : D
rachylou, the lighting situation is just overhead recessed lights in that room and the kitchen. In the LR, they can't even be dimmed. As mentioned above, I have to get some kind of lighting strategy. I agree about the accent color. I'd probably go with some kind of tomato red. Something bright and punchy.
I am already thinking post-sofa and armchair...I am not happy with them (less unhappy now with the reconfiguration)....they're too dark and bulky, even if incredibly comfortable to sit or nap on. But for now I have to work around them. In this position, the sofa really swallows up the room's width (even though I like it better now).
Astrid, I hope I can inspire you! I remember being young, not having any money, and also renting places so that I was limited in how I could change my environment. Very challenging. But there are always things you can do.
Maneera, you've given me so many salient and detailed recommendations, I don't know where to start! I still haven't had a chance to stop and analyze most of them. But your experienced eye, love of design and capability is clearly evident.
I will be coming back here to comment on everyone else's excellent advice....thanks again!
