Tony,
If I may 2 questions;
1: I can imagine the copper leaves being cut, beaten and chased to create the shape and veins etc, but in your previous posting there was a pewter lizard, did you wife mould that as well and if so what method does she use (lost wax?), and
2: What else is she using to create such wonderful sculpture, for example the torc's in Boudicca's Hoard.
Any answer gratefully received.
