Mokume Gane is a traditional Japanese method for laminating various colors of metals together and manipulated them to create patterns that resemble wood patterns. Polymer clay lends itself perfectly to creating patterns from layers of oven-bake clay, manipulating them and removing slices.
Layers of clay are manipulated with rubber stamps, texture sheets, needle tools, balls of clay strategically placed under the stack and found objects. Gold, silver or copper leaf may be added between the layers of clay for some very interesting results.
