I have 3 sizes that I make these metal ring dishes in, this is the largest one. It starts with a 3.5" aluminum disc that I hand-stamp letter by letter, and then I slowly hammer it into shape as a dish, working my way down into smaller dapping blocks until it has a perfect little curve, and then I flatten out the bottom. The aluminum is very light weight, and it's the perfect little size to keep on a nightstand or on a windowsill by the sink to hold a ring. These larger ones take quite a lot of time to hammer away into shape, but I love the result!
This one features lyrics to the gorgeous Phish song "Shade".
