My 4 year old daughter and I walked around the woods in the Bronx and picked up leaves (Sweetgum, Dove Tree, Fig, European Beech, Magnolia, and Pine), branches and corresponding fruits (nuts) that we found on the floor. The leaves were wet so we allowed them to dry for a few days. We purchased a large cardboard display board (1.5 feet by 2.5 feet) for $1 and wrapped it tightly with left over burlap fabric that was in the garage; stapling it copiously where necessary. We used industrial strenght glue ($5) to adhere the leafy and woody objects to the burlap/cardboard frame. We call it "Fall" and it hangs in our living room.
