Then let your glue gun heat up, while the glue is heating up take the time to paint the lid any color you want. After that start glueing the marbles on to the jar, until the jar is completely covered.
After the jar is covered let glue and paint dry, then take a battery powered tea light and place in the bottom of the jar, put the lid on, then watch the magic. This is a beautiful piece for dinner parties, night lighs or any kind of thing you might see useful.
