Shelf base. Aplied model train grass paper bought at Toys R Us. Bought Tree plant at Wal-Mart and cut the tree trunks into 11 inch high pieces to make the tree trunks surounding the Plaster Heads. Plastic leaves were hot glue gunned to the trees and top of the shelf. Used Super Sculpey to make the Gungan Sacred Heads and made a mold from which I made 2 plaster copies. Then Sculpted tree roots down the main face where Boss Nass stands and speaks to the rebels.
