we've just bought a house and my son's room requires major redecorating as 3 walls have a beige fabric type wallpaper, very old and turning yellow. This wallpaper is grainy and rough to feel. is it possible to paint over it? I heard it would be a nightmare to take off. One piece is already curling off and if you try and pull it further the backing stays behind. If not ok to paint over, any other ideas would be appreciated. thanks.
