I made the valence above the bed. It was pretty simple. I hung some bamboo ($0.80 each) with fishing line then draped fabric over them. I had to tie the fabric on with a bit of thread. I bought the fabric from the sale bin for $4.00.
The chair is second hand. There is a blanket draped over it so that it will match and has a reading lamp near by.
The comforter was $30. I got the throw pillows and bundled sticks on sale as well. Overall, this room was pretty cheap to put together.
