Here's how you do it:
• Roll out a slab of metal clay to the desired thickness.
• Place a scrapbook sized stencil over the rolled clay and spacers and roll again. Do not reduce the thickness of the spacers. The stencil should be thin enough that it will sink slightly into the clay and leave a shallow relief pattern.
• If you'd like to impart a textured surface to the design, roll the clay as described above, lay down the stencil, then the lace or other texture, THEN re-roll to impress both the stencil pattern and the texture at the same time.
• Experiment with lace, a skeleton leaf, tearaway textures, or other very thin material that is flexible enough to work with the stencil.
• A variation of this technique would be to roll the slab, re-roll with just the stencil, then before removing the stencil, texture the pattern with a mascara or toothbrush, ball burnisher, or other tool.
• To make the pattern completely unique - use a jewelers saw to pierce a design out of 26g brass.
