The idea is basically that it would be great if there was an option for characters to make items, jewelry, and trinkets from various metals and precious materials. This would be great for things like glasses, but I can also imagine mixers wanting all kinds of odd little trinkets or jewelry (like a bullet necklace), and a crafts person eventually getting skilled enough to make fancy custom jewelry that corpies would love (‘Oh my beau had this handcrafted by Joe Baka’).
