Whether you're renting, have a condo, or own your home outright, we all have at least one thing in common...at some point in time, there will be a ding or hole in your wall that must be repaired. But driving all the way to the hardware store for spackle is so involved. Instead of doing that, grab a few items you already have around your space and get to sealing.
For smaller holes, squirt some toothpaste in the spot you're hoping to cover (only use white toothpaste), smooth it over, and let it dry.
The finished texture is actually fairly similar to spackle.
If you don't have white toothpaste, turn to your standard bar of soap.
Get it wet and rub it into the hole until it's filled.
For a stronger solution, mix some baking soda with a drop of super glue using a toothpick.
Quickly cover up your hole. Once it's dry, sand the spot down until it's flush with your wall.
This heavy-duty fix is for bigger holes (two to four inches in diameter): cut a square cardboard piece out that's a little bigger than your hole. Poke two holes in the center and weave a string in through one and out the other.
Squish the cardboard in the hole, making sure all corners are inside and the strings are toward you. Then, mix one tablespoon flour, one teaspoon salt, and a few drops of water. Add the solution to your patch so that it oozes around the cardboard's edges, binding it in place. Let everything set, and then pull the string out. Add a second coat of the paste and smooth it out with the wall.
