Using Rocks' Natural Cavities for Candles

• 1). Pick up rocks that have natural cavities. These rocks may have bubble-shaped holes or a deep wear spot where water dripped for a long period of time. The bottom of the rock should be flat enough to sit level and not tip over.
  
  
• 2). Hot-glue a candle spike to the rock at the indentation. These spikes come in a variety of sizes.
  
  
• 3). Press a pillar-type candle onto the spike. Place small felt disks under the rock to prevent scratching your furniture's surfaces.
  
  

Drill Holes in Rocks for Candle Holders

• 1). Set up a drill press with a variable-speed heavy-duty drill. Attach a diamond-bit hole saw to the drill. Position the drill press over the stone you want to drill. Clamp the stone in place using extension-type wood clamps that will hold the stone securely while you are drilling.
  
  
• 2). Wear safety goggles. Roll out a rope of plumber's putty so that it forms a ring that is twice as wide as the hole you want to drill. Press this putty around the location of the future hole.
  
  
• 3). Fill the putty ring hole with water. Diamond bits require water to cut through stone. The water keeps the bit cool while it works. Cut the hole to the depth you desire. Attach and use a smaller diamond bit to help you clean out the waste in the hole until you have a finished hole that is the depth you desire. Make sure your hole stays full of water while you work.
  
  
• 4). Clean off the putty, unclamp the stone and hot-glue a candle spike to the bottom of the hole. Insert a pillar-type candle and press it onto the spike to hold it securely. Position small felt circles under the rock to protect your furniture's surfaces.
