Hi Everyone and Many Thanks!!!!
This piece is 4"x4". The bottom layer is hammered and colored by liver sulfate. The top piece is started by drilling a hole and feeding the saw blade through. I believe I used a 4/0. I found that a good quality saw frame allowed for much greater detail. I switched part way through the project :). Bees waxing the blade was also a big help. The center upper heart shape is a rivet, as well as the birds nest, and corners.
