Moved into a very large house that is over 100 years old. The plaster on the walls are cracking and also breaking off in large pieces in all the rooms. We want to put some type of wall covering over it (but not drywall) and then put either a textured plaster or wallpaper on. Need advice on how to remodel these walls and what are all the opitions out there to use as a wall covering. I have pic's of the walls but could not get them to upload.
