Place the texture design in the center of one of the squares. Place the other metal square on top, sandwiching the texture piece between the metal sheets. Place the metal "sandwich" in a folder made from an old manilla folder or a piece of thick cardstock. Hint: As metal is run between the mill rollers, the pressure pushes on the metal, causing it to lengthen slightly. The greater the pressure, the longer the metal "grows." Because of this, all designs will become slightly longer. Therefore, a circle will become slightly oval. This should be kept in mind when deciding how to place a texture design shape on the metal.
On the off chance that it might work, I tried the following and it worked quite well!
A: Follow Steps 1-3, cutting two cupcake wrapper designs of the same shape. Annealing the metal for this technique is very important.
B: A must: Lightly coat the back of the cupcake wrapper cut out design with stick craft glue and adhere it to the center of an annealed metal square. Note: In my excitement to try this, I did not glue the design down and ended up hammering my fingers as well as the design.
C: Place the square on a bench block, cupcake wrapper design facing up.
D: Use a hammer with a large, flat smooth face to hammer the cupcake wrapper design into the metal surface. Use firm flat strokes. Notice that the metal around the upper edge of the design is no longer smooth. Something to be aware of: Because it was close by and this was just practice, I used the hammer set aside for use with stamps, so those hammer face marks transferred to the metal.
E: The paper design should easily pull back from the metal when finished. If not, it will come off in the next step,
F: Rinse the metal to clean off the residual glue and/or paper still stuck to it. Dry.
G: Repeat the steps with the other annealed metal square. Move on to Step 6.
