Setup, practice, and planning
Your workspace should be a strong, sturdy table. A wobbling surface will cause your metal and tools to bounce, creating a slightly shadowed impression when stamping. A stable table provides the resistance you need for a sharp, clear impression.
If you’re new to stamping on metal, start with simple design stamps. They will impress correctly every time, and once you master them you can move on to more detailed stamps.
Practice first on inexpensive 24-gauge copper sheet: Place the copper onto the bench block, and set the design stamp flat against the metal so that it is straight up and down. Strike the stamp once or twice with the mallet or hammer, making sure your hammer comes down straight and centered onto the back of the stamp. If your impression is too light, strike your stamp a little harder next time or switch to a heavier hammer. If your impression is distorted and very deep into the metal, you may need to lighten up on your strike.
For larger stamps, you may need to “tilt and tap” to get the whole impression. This means striking the stamp multiple times while very slightly tilting the stamp to catch all sides of the design.
If desired, pre-plan your design: Trace the 7⁄8-in. (22 mm) circle blank on a piece of paper, and gently press your stamps into the paper as you would like them to appear in your earrings.
