LINES

Hold a chisel perpendicular to the bench, with the blade oriented across the tubing. Hit every 3 mm along the length to create a series of depressed lines. Anneal the bracelet. For steeper ridges, angle the chisel 45 degrees (as shown) and hit into the existing lines. You can also create zigzags, steps and many other designs by holding the chisel at different angles to the tubing.
