Gold Vases

Select your jars and make sure they are clean and dry.
Punch or cut some dots, stripes or any other shapes (same or different sizes) from your stickers.
Stick them on the outside of your jars, creating a nice pattern. Surfaces that are covered with stickers will appear transparent once you complete your vases. Make sure stickers hold well to the glass without any gaps otherwise paint will leak through.
Once you've finished with your desired pattern start spraying the jar with the paint. Secure the jar opening with a wide round sticker to prevent the color from going inside the jar. It will probably take more than one coat to get an even coverage.
Let the jars dry completely. Once dried carefully remove the stickers. If any of the color leaked inside your dots or stripes use acetone and cotton swab to clean.
