Cutting a hole in a glass bottle is a great craft idea. First you will need to mark the area you want to cut with a sharpie. Then, wearing safety goggles, rubber gloves, and a long sleeve shirt, slowly drill a hole using a diamond drill bit. Make sure that you mist the hole with water every few seconds as you drill, as this will stop any shards from flying around and help reduce breakage. Remove
. excess glass around the hole with a damp cloth, and polish the hole using silicon carbide sandpaper. Remember to do everything slowly and gently to reduce the risk of breakage, and do not take off your goggles, gloves, or long sleeves until you are completely finished.
