Here's a pretty typical toddler's room. The dark window coverings and knotty wood paneling make it a bit dark and dreary. Jump below and see the amazing transformation this room underwent.
Wowza! Yes, this is the same room and the paneling is still there but it's now concealed under a nice coat of creamy white paint. The dark drapery has been replaced with white breezy curtains. There are a lot more changes in the room (for example, a "new" bed frame) but the biggest impact came from the freshly painted white walls and removing heavy dark drapery - two very inexpensive fixes that can change the look and feel of a room instantly.
