I'm hoping someone may be able to advise me. My living room is covered in textured wallpaper which has several coats of paint on it. I want to create a feature wall, using a contrasting paper and I guess I'm looking for an easy answer. Is there a product which is easy to use (I'm a DIY novice ) that will cover up the paper on the wall I want to change, rather than having to go to the trouble of stripping off the paper and possibly damaging the paper that I don't want to change?
