For this project, you will need:
-- Mason jars
-- Black paint marker
You can find all of these items at a craft store.
Clean and paint your jars
Make sure your jars are clean from any food or labels. Then, use the spray paint and paint the entire outside of the jar. You want the paint to be translucent, so one coat should suffice. You can check this by setting a lit candle inside. If you want it to be a little darker, you can add another coat of paint. Let the coats of paint dry completely.
