Cute idea for Halloween decorations. Paint maple leaves (from the yard or the craft store) white and cut out or paint eyes and mouths. Create a garland by attaching ghosts to twine with glue or mini clothespins.
hedgehog fall leaf craft - I did this with my son's class and it was a total hit. I'd recommend using leaves that aren't brown yet, as the brown leaves are more brittle and hard for kids it work with.
