You may recognize "Collateral Damage". This was a piece I made to show the destruction of forest land for housing developments on huge lots.
The "leaves" are small bits of hand dyed scrim that were stitched in place.
I drew these "Roots" and had thermofax screens made from the sketches. The roots are growing into the "blood" of all the animals who lost their homes so people could have huge lawns for their McMansions.
This is the forest floor and rocky layers underneath using raffia, tied balls of thread, flat rocks, hair mats from my dogs fur and sari yarn to represent rocks.
This area has sari yarn, rock, and dyed silk chiffon filled with stuffing to represent the rocks. The subsurface is made with tucks of dyed rayon fabric.
