I would like to paint a wooden flooran i would like to wallpaper over paneling. I also would lie to do a Winnie the Poo theme in the babys room. Panrling goes halfway up the wall with a cair rail between uper and lower wall. I was going to paint the ceiling and upper wall with a sky scene and paint the paneling with the scene to be at baby's eye level with trees extending uup into the sky area to be a little more interesting to acult6s to view. How do I camaflage the line between paneling & upper part of wall. What is the preparation for the paneling.
