A good work surface is a necessity. Glass, acrylic, marble and Formica are all good surfaces to work on. The oils in polymer clay may damage wood finishes, so it’s best to avoid these surfaces. Clay sometimes sticks to very slick surfaces like glass and marble. In warm climates, the cool temperature of surfaces like marble may help maintain a level of workability and prevent your clay from becoming soft and sticky. Always remember to clean your work surface before and after you use it.
