I decided to renovate my guest bedroom.  The walls were a pale beige; I decided they would look better as a bright blue.  I went to the hardware store and found a color of paint that I liked.  I asked a friend to help me move all of the furniture away from the walls and take down all the pictures.  We put down tarps on the floor so that paint did not get everywhere.  I put down painter's tape along the molding so that they did not get painted.  It was a lot of work but we got the room painted in a few days.  Once the walls were dry, I painted the molding along the floor with fresh white paint.  I got inspired after the painting and set up a new set of wooden shelves, painted the same white as the molding.  Then we moved the furniture back around until the room looked nice and fresh.
Why did they renovate the room?
