This is a flexible, rubber texture plate with an all-over pattern of circles and lines, bursting with life and energy -- lots of movement! You can see the example above that I fired in bronze. Metal clay and polymer clay enthusiasts alike will find it useful. The design surface is 10.8 cm X 10.14 cm / 4.25” X 4.12” and the depth is approximately .5 mm. Nice and large if you want to make large or longer things.
