I bought a package of orange tissue paper at Wally's world for .97 cents.
Cut each sheet in half length wise. You will have enough to make 16 Jack o jars, if using quart fruit jars.
Use black construction paper to cut out the eyes, nose and mouth. Stick on with double stick tape.
Wrap tissue paper around and fold on the bottom of the jar.
Insert a tea light candle (that's what I had on hand, or votive but then you're gonna have to clean the jar.
Light and your done!
