1. Apply a coat of varnish to the casting and let dry. 2. Carefully cut out the grape design from the casting. 3. Paint the grapes several shades of purple and lavender and the leaves in varying shades of green. 4. Apply another coat of varnish to seal the paint and let dry. 5. Cut colored paper to the size of the label you want on your jar (or use store-bought labels). We glued together 2 pieces of paper, the larger one behind made a border around the label. 6. Glue the grape cutout to the center of the label. Glue the label to the jar.
