TIPS FOR USE ON CLAY: Since different clays have different features, there are clays which are sticky than the others & so affect the pop out effect, in this case we would recommend: - For polymer clay, bake your clay right in the mold without concerns of clay distortion from de-molding. -Put the caly into the fridge for around 5-10 minutes.
