Jalan Hassanudin in Denpasar is not too far.
Stroll the 20 or more gold shops (Toko Mas) and see what they have, but also have a look around the back down the alleys as there are some small manufacturing places there that may be of interest.
You may also be able to buy beads or other "do it yourself" stuff.
Somehow I doubt formal classes in making things, but if go into some of the larger beads shops (plenty around Seminyak) and ask, they may be able to help you, perhaps informally.
