Start by tracing your child's hand onto a piece of green construction paper. If they're old enough they can do this themselves!
Using scissors, (age-appropriate) cut out their handprint. Using that as a template, trace it 4 more times so you have 5 handprints total.
Cut out all the handprints.
Place one handprint and then align two horizontally and glue together, almost making a triangle. You want one with their fingers pointing forward or up, one pointing to the left, and one pointing to the right.
Using your glue stick, glue the handprints together. Add another layer of handprints.
Finally, turn the papers over and glue on a gluestick about halfway down. Make sure you'll be able to wave the leaves (handprints).
