Let the jars dry. Much like a decoupage. With permanent marker add child's name and date to the bottom of the jar. Add a votive. When they get home they have a wonderful, keepsake to use year after year.
Children decorate their bags.
Children fingerpaint on paper then stick on fences, pumpkins, moon, and ghosts. Shake cotton balls and paint in the bag. Glue the yarn on both sides of the paper plate. Glue black hat on top of plate. Glue buckle on hat.
