Leaf rubbings are a fun, inexpensive and attractive craft that kids of all ages can do. These can be as simple or decorative as you and your children want to create.
So gather some leaves, fall colored crayons (remove the wrapper) and blank paper or tissue paper (be careful it will rip easily).
Place the leave vein side up under a piece of paper on a flat surface. Rub with the side of the crayon in a back and forth manner on the white paper over the leaf. Repeat this on the same sheet of paper using a variety of different leaves and colors of crayons to create an interesting piece of art.
