Texture hammers are a great option. A variety of pre-textured metals are available as well. Those shown are 24 gauge brass sheets that can also be used in the rolling mill to imprint a reverse image on softer metals.
Patinated metals are available in a variety of beautiful colors. These can be riveted, not soldered, in place. Soldering will destroy the beautiful display of color. After the cuff is completed, these should also be sealed with an acrylic sealer or Renaissance Wax to preserve the patina.
Two of the cuffs have words stamped on a separate piece of metal which was then soldered to a textured piece. 3mm or 1/8" upper case metal stamps were used on scrap metal pieces. After stamping, the scrap was cut to the desired size and the edges filed, sanded and refined.
Metal Clay Embellishments:
Solid embellishments such as copper, brass and silver can be soldered to a backing to be attached to the cuff. Make sure that the piece being used is not plated as some of the materials under the plating can easily melt before the temperature needed for soldering is even reached.
Use hole punches and circle punches in scrap metal to create these embellishments. Each will need to be hammered flat before use as the metal is slightly cupped (shown in the photo on the right) by the cutting action of the punches. Argentium scrap was used here.
