Ive been reading the comments and am thinking about crackling ,with Ralph Lauren crackle paint, or either the antique leather paint, one wall which is currently covered over in wallpaper. Will it be alright to crackle over paper? Or remove it? Sizing was not used and it will be a PITA to remove it.I was hoping this cracle would be easily to do, but from what im hearing it is not going to be. Im a regular paint user, and have never "fauxed". Now im scared......any encouragement out there? I really llike how it looks in the paint sampler. Any comments will be appreciated.........Thanks in advance.
