Print the skulls onto regular copy paper.  Then determine which of the skull shapes you want to use.  Cut it from the paper with scissors and use regular tape to secure it over the masking tape.

Use a craft knife to go all around the outer edge of the skull as well as the eyes and nose in the center.  Be sure to cut through the paper template as well as the masking tape.  Do any inner parts like the eyes first then do the outer parts.

Remove the pieces that you cut and you are left with a skull shape on your mason jar.  Repeat with as many jars as you would like.  I did a different skull on each jar but you can definitely do the same on each one.

Then take your jars outside for some spray paint.  Spray paint them black first.  Allow to dry then go over the top with the purple fog color shift paint.  Allow to dry before continuing.

Use your craft knife to help you get under your masking tape and lift the skull shape.  You can also cut any paint that may try to peel away with your masking.

I feel that just about every project is better with a touch of glitter.  This step is optional but I love the look it gives these Halloween lanterns.  I used just one coat of Testors Intense Glitter paint just in the area where the paint was masked for the skull.  Then just allow it to dry.

Pop in a candle and your Halloween lanterns are complete!  I love the look of the glitter on the skull and how the light shines through!
