The copper was textured with a crocosmia leaf from my garden which makes it very personal - nice to have a relationship with your jewellery. Lots of people in my class bring back things from their holidays and set them in silver e.g. lava stones from Iceland and ancient petrified wood from Californian forests.
As this is a no solder project it allows me to have silver earwires so no problems with tarnishing my ears! I didn't have the right size of copper wire but used 1.00mm which made the wirework a bit more difficult but my little scalloped bucket still swings nicely on it's handle.
