1) Due to  fall season, we had lot of  dry leaves in our garden. (image 2,3)

2) Collected  all those dry leaves in a plastic grain bag bag and hit hard on

     the ground floor, then crushed so that the dried leaves breaks in to very small pieces   
     in the bag.
3)Put those broken leaves in small paper bag  then pressed hard inside and closed the
     bag by stapling. [size H-6 inch X W-2.5 inch X L-2 inch] (image 4, 5)
