Mason Jars - Frosted glass look. Just create your own shape with contact paper.stick it on.spray with frosted glass spray paint.then peel of your contact paper shape.and voila! These look like recycled jars too.
Etched jars - ones that you would normally throw in the recycling bin! You could skip the etching cream and go for the etched glass spray paint it has the same effect but less time and money especially if you are wanting them for a table decoration for
