Help me decorate my guest room?

[Amber T.]

I'm decorating my first guest room, and I'd love some suggestions! So far I have a queen size bed with a black frame, pretty damask striped grey sheets, a white comforter, some pillows with white cases and some with grey cases (matches the sheets), and a black throw blanket at the foot. I also have a black and white picture (decent size) in a black frame hanging on the wall. I only have one table and it's hideous so I need to get a tablecloth, and I'd like to get some curtains as well. I don't know what color tablecloth and curtains to get, or if I should add anything else (small) to the room. Any thoughts? Oh, and on the table there's a lamp (silver base, white shade) and a poinsettia plant. I know it's not much, but I'm excited to have anything to offer guests and want to make it as cute as possible!
