Fill the toe of a nylon sock with grass seed. You can also cut the foot off a pair of old pantyhose.
Add sawdust or soil to the sock until it has a ball shape.
Tie the nylon sock closed with an elastic band. You can also tie the nylon into a knot.
Decorate the grass seed head. Glue on wiggly eyes, draw on a face with permanent markers or glue on felt pieces cut out to resemble facial features. Encourage your child to be creative and have fun when making the grass seed head.
Place the grass head on a dish with the grass seed end facing up. Water the grass seed head daily to keep it moist, and place it in a sunny location.
