1. Select a smooth, glass vase without any grooves, raised designs, or embellishments. The best type of vase to use is one with straight sides. You can also use a clear wine bottle or a mason jar.
2. Wipe the vase down using a cotton ball and rubbing alcohol. This will get rid of any oils that might prevent the paint from sticking. If the vase is especially dirty, wash it using soap and warm water.
3. Wrap rubber bands around the vase. You can position them straight across, at various angles, or a combination of the two. Don't be afraid to overlap some of the rubber bands either! For a more interesting design, choose a variety of rubber bands, both thick and thin.
4. Take the vase into a well-ventilated area and place it upside down on a sheet of newspaper. The best place to work would be outdoors. If you can't work outdoors, make sure that you have plenty of windows open. Cover your work surface with newspaper, and make sure that there's nothing nearby that can get ruined.
5. Spray the entire vase using short, even strokes. Shake the can until you can hear it rattle, then hold it 6 to 8 inches (15.24 to 20.32 centimeters) away from the vase. Apply the sealer in quick, even strokes. It will take about 10 to 20 minutes for the paint to dry.
6. Apply one or two more coats, if needed. Allow each coat to dry for 10 minutes before applying the next one. If you are working with "frosted glass" spray paint, don't worry if it looks clear at first; it will look frosted once it dries.
7. Allow the vase to dry overnight before removing the rubber bands. If a little paint got under the rubber bands, use your fingernail to scratch it off. If there is a lot of dust on the vase, wipe it down with a damp cloth.
8. Display the vase. You can use it to hold flowers or candles. You can even make it fancier by wrapping a pretty ribbon around the center.
