This is the copper cuff that you have been looking for. It is lightweight but a sturdy piece of modern metal jewelry.
After I cut the shape of the cuff, I used my saw to make three openings down the length of the copper piece. Then I gave it texture with my hammer and formed it over a bracelet mandrel and then opened out the width to make this gorgeous copper arm band.
The width of this cuff is 2 1/2 inches at it widest point.
