I have removed all the wallpaper and the border that was at eye level in the bedroom, I have repaired the walls, stained and washed the walls. Now after painting there is a shadow top and bottom of where the boarder was. Now what?? I have no idea how long the wallpaper had been up, just bought this twenty year old home. I know the previous owners had a 3 yr old girl, as this has to have been her room with all the pink, I am gonna guess 3-4 yrs.
