Cut all of your pieces from glitter cardstock. For each jar, you will need a circle to cover the mason jar lid as well as a spooky shape of your choice.
Prepare the eyes by removing the post on the back. I used an old pair of scissors to cut them off. If your google eyes do not have a post, you can skip this step.
Use hot glue to secure everything to the top of the mason jar. Add the circle to the top of the jar lid then add your shape as well as the cat eyes. You might want to also secure the band to the lid so it will all stay together when removed from the jar.
Then just fill your jar with the candy of your choice and put the lid on top. These are ready to be delivered to your neighbor, friend, or handed out at a fun Halloween party.
