Mass with Wood Arrangement

Most of the time I am able to pick the materials I need from the surrounds of my house for my Ikebana class.
For this assignment I did it as a rustic fall arrangement.

Hydrangea, Twig and Driftwood
I finished this arrangement in 10/2/2012 class.

Butterfly bush, Cat tail, Hosta and Dragonhead  in the
 dish Kenzan behind the wood.
