Another Room Almost Finished

Here's a picture of our den. Arranging furniture in this room has been a bit challenging. It's large, but laid out strange. I have a large plant that is going in the corner between the bookcase and entertainment center. I also need drapes of some sort. I need to figure out where in the house to put the computer. I really want something that closes up so it is hidden. I also would like to fit another bookcase or two in for Dale without having a cramped feeling or looking awful. I'm thinking maybe the laundry room? Some day he'll have a home office again with wall to wall bookshelves, I'm sure.
