I finally got started on the first copper bracelet! It was pretty easy to bend around the mandrel for the initial wrap. Having the wire inserted before wrapping made a big difference. Instead of 10G copper wire, I used 16G Brass wire.
I did cut the brass wire too short and I definitely have tool marks, but since this is the practice bracelet, it is ok. I still will hammer down the front to make it flatter and use this bracelet to practice the texturing of the copper and giving it a patina. Peace.
