I am in love with the #7/0 Herkules saw blades! They can actually cut the tiniest details from tin, once you get the hang of it. Here's my latest -- doves cut from a floral tea tin, riveted onto a blackground (also tin), and collaged on the back with a beautiful French handwritten letter, possibly a love letter; I saw the word "coeur" which I do recognize, although I don't speak French, more's the pity. These are really pretty on; the doves flutter. They're available in my Etsy shop.
