Accidents happen!

And a hole in the wall is nothing a little drywall, spackle and paint can’t fix -- as long as you master the technique.

When Ty Pennington from TLC’s "Trading Spaces" reboot visited our show with his castmates, he gave an important reminder: You have to fill the hole before you spackle!

And while you can use cardboard, Ty suggests drywall since it’s the same thickness.

Now, chances are your hole isn’t a perfect shape, so the TLC show’s carpenter suggests tracing something circular (like the top of your spackle container!) and cutting a perfect circle into the wall.

(Hey, what's a bigger hole, right?)

Then, cut a circle of the same size out on a spare piece of drywall, apply drywall tape to it -- and fit it right into the hole in the wall. (Try to make it as flush as possible!)

Okay, THEN it's time to apply spackle.

After you let the spackle dry, sand down the outer edges with sandpaper -- or a wet sponge, Ty says.

Then, paint over the spackle, and voila -- goodbye, hole!
