Anyone have any suggestions for which gauges of copper sheet work well for someone that's teaching himself repousse? I'm having a ball with copper flashing, but would like to try for something thicker.

Depends on the overall size of workpiece, and height for pattern/design you want to raise,
Old copper water cylinder tanks can be used or up to 0.125" for something like a weathervane body, Just keep it well annealed and keep re annealing as necessary as you are working the material it will work harden
You could even use copper foil and a ball pointed tool to inscribe patterns for jewellery etc,
Give each a try, there are no hard and fast rules but don't forget enjoy yourself while you are doing it.

From everything I've read and with the "little bit" of experience I have on the subject, 32 ounce or 18 gauge (.043) copper is good size for doing repousse (and raising also).
