The 6 accurate, detailed leaves in the Leaf Replica Set have been cast in flexible material for use in art projects or as study tools for plant identification. Molded from acutal specimens, the set includes Sugar Maple, White Oak, Red Oak, Elm, Tulip Poplar, and Ginkgo. Create colorful leaf prints using stamp pads, block printing ink, and rice paper. Attach leaf replicas to wood blocks using vinyl glue to construct leaf stamps. To keep your leaf replicas fresh, wash occasionally with warm soapy water and air dry. Leaf replicas are recommended for ages 8 and up, with adult supervision.
