Place the ceramic pot upside down on a damp cloth laid out on a solid surface. The moistened cloth ensures that the pot won’t slide.
Press a nail into the ceramic to nick the spots where you want to drill. Drill a larger hole in the center or three smaller holes in a triangular pattern. The indentations keep the drill bit from sliding.
Equip your power drill with a ceramic bit, which is designed to prevent the pot from cracking or chipping when drilled. You can buy ceramic bits at a local hardware store.
Dampen the bottom of the pot to prevent the drill’s friction from overheating it, which can cause it to crack.
Drill into the markings, applying steady, easy pressure directly downward.
