Repair Damaged Wallpaper

If you have to repair a damage in wallpaper, use a piece of paper slightly large than the hole and with a matching pattern to that which has been damaged. Paste the new piece over the hole matching the pattern exactly.

In order to get an invisible join it is best to tear the paper being used for the patch instead of cutting to shape with scissors or a knife. Using knives or scissors gives more prominent edges whereas tearing the paper "feathers" the edges which will be less obvious when pasted to the wall. You can try tearing plain paper first just to get the hang of it.
