On the photo above you can see the copper piece, this is what I made. I originally attempted to make it from fabric however the shape was wrong and I couldn't get the edges to point enough.
So to make copper piece I got a 0.5mm of flat sheet copper. I drew around my card stencil/pattern piece . I then began to cut around the pattern using pliers.
Once the shape was cut I sanded the edges with a metal sander, always going with the grain of the metal.
I then layer the pattern piece on top of a metal block and hammered out any uneven surface with a plastic hammer.
Then finally I measured and marked some drill holes where I could attach the pattern piece to my dress. 
I drilled the holes wearing protective goggles and tieing my hair back for safety reasons. Once the drill holes were done I filled down the rough edges if the holes, once this was done I was finished.
