I am decorating a room where there is 1 bad wall which is the wall where the chimmney is, I will be putting an embossed wallpaper on it and to help with the finish. I intend to put lining paper on first just on the 1 wall. I have never used lining paper before and not quite sure how to attach it to the wall. Do I put it on the wall Horizontally and then hang the other paper over the top as normal?
Thanks.
