Walnut Tankard with Copper Hoops

Walnut is the darkest of the woods I routinely use, and is usually a dark chocolate colour, although it often contains lighter streaks. I think the copper hoops go weIl with dark wood, and when you see the Walnut tankard with copper hoops by firelight, the effect is particularly fine. I'd like to make more, but it's probably going to be a one-off because copper is too expensive for routine use.
