You could spend your whole life ticking house chores off your home maintenance list. It seems as though taking care of your home is a never-ending job, and this is especially true when you have holes in your walls. But while you could head out to Home Depot and buy some filler, this old-school hack involves toothpaste instead. In fact, you can use this toothpaste as a putty to fill the holes with ease.
When the toothpaste has dried out, you can then sand the area and paint over it. And within just a few hours it'll be like the holes were never there.
