I model central California and need realistic bushes to complete my scenes. I model the gray sagebrush using faux fur. This is my method for the green leafy bushes and small trees like here at Port San Luis Obispo.
I make bushes from polyfiber, faux fur and foam. I make sagebrush from the faux fur.
I once colored my own polyfiber using quilt batting and a fabric paint called Dye-na-flow.
Here are polyfiber and faux fur bushes planted around our metallic cardboard balloon pond.
Black batting is now available. Just Google "black batting"
