Fill Nail Holes With Homemade Spackle

If your walls are pockmarked with nail holes, instead of tossing down money on spackle, make this smart concoction instead. It's as simple as mixing together equal parts cornstarch, salt, and water into a thick paste. Dab the homemade spackle over holes, smoothing with your finger. Once dry, touch up with paint, and your walls are free of holes.
