Filling a door knob hole in Sheetrock with newspaper followed by Spackle is an effective method due to the newspaper's ability to help fill the void and prevent shrinkage when it dries. The use of newspaper serves as a cheap and lightweight backing for the Spackle, which is a common drywall compound used for minor repairs. When Spackle is applied over the newspaper, it helps create a smooth finish that can be sanded and painted over to blend with the surrounding wall.

Using this method is advantageous because it takes advantage of readily available materials and provides a solid base for the Spackle, ensuring a better adherence and a more durable patch compared to just applying Spackle directly into the hole without any backing. Additionally, this approach can effectively fill the hole and restore the integrity of the wall.

Other methods may not provide the same level of effectiveness. For instance, using plaster might be more cumbersome than necessary for a small hole, while installing a larger plate could be overkill and could complicate the aesthetics of the door. Covering with a wood patch may also alter the wall surface inappropriately, especially if the surrounding is painted, potentially requiring additional work to achieve a seamless appearance.
