Okay so what you are going to need is;
copper/bendable metal band
a round mold (optional)
Now that you have all of your tools place the copper/metal (bracelet base) on the Masons stone.
Put a piece of tape on the copper/metal band. This will make it so that your stamps will be even and more neat looking.
take a metal stamp and push hard into the band. Now take your hammer and gently hammer the stamp into place, remove the stamp after 10 hits.
Now take your mold (must be firm) and start to wrap the band around it. Make sure the bracelet doesn't brake. Do this slowly.
Make sure to sand the sides of the bracelet because the copper/metal may scratch you so be careful.
