My daughter and I attend a playgroup, and this past week our activity was to create footprint ghosts. I thought they turned out super cute, and are really easy to do, even with a (almost) two year old!
black construction paper
First, paint the bottom of your child's foot with white paint. Then, press their foot onto black paper.
Once dry, glue on two googly eyes. Then, cut around the edge of the white, leaving a small border of black, and glue a magnet to the back (I just cut up one of those free flat advertiser magnets).
Voila! A Halloween keepsake/fridge magnet! Grandparents be watching - you'll get one in the mail soon!
