How do I cover a hole in wallpaper?

How big is the hole, if its a small hole you can add a tiny piece of the same wallpaper to blend in.

OR if its big hole you will have to do some creative patch up work with the same wallpaper. You would have to patch the hole with with spackle then after it dries match up the design.

How big is a hole?

Smooth the paper back over and use glue to patch. If you don't have the original paper left see if you can find a place where you can steal a little piece from like under a receptacle cover. You can paint the wall to match with acrylic paint. If the hole is big then you may have to hang something over it again like a cute plaque.

Is the hole big or small?

I’d fill the small hole with spackling compound & then use paint or markers to color in the hole.

You could patch it and paint it a similar color or hang a different piece of artwork

Do you have an extra wall paper? IF yes, just line that up and you are good to go!

I would try patching it if you have extra wallpaper. Otherwise, I’d put up a wall hanging or new artwork.

If you don't have another piece of the wallpaper, you can try freehand drawing the design or just hang something else on the wall! :-)

Maybe get a paint pen in the right color and just touch it up carefully
