What you will need:
Using a spot outside, place your cardboard on the ground for less mess. To start off this project, you are going to fill your spray bottle half way with water and the other half with vinegar. Give it a good shake to mix it up. Then shake up your looking glass spray paint, so your ready to start. Lay out your glass containers, evenly spread out, on top of the cardboard. Start spraying the inside and outside of each glass container. If you are using a bottle or something with a narrow opening, just coat the outside with paint.
This is the messiest part, so I suggest wearing gloves and clothes you don’t mind getting dirty.
