Can you tell what plant Larkin is re-creating? Hint: you saw the bloom last week. ;)
First, Larkin cuts the shape out of sheet silver.
Then they scored a line down the center and emphasized it with a chisel so it has a slight center fold.
Larkin then rounded the shape out with a ball peen hammer on a wood block.
Finally, the edges are rounded and given their final shape and the whole thing is hand polished, especially any remaining chisel marks.
