When you are completely new to Polymer Clay, having someone to explain the basics can be helpful. Below is a short 10 minute video which explains all about conditioning the clay, which means softening up the clay to it is ready to use, and also about mixing the colours. There is also a worksheet which accompanies it if you prefer to print it out. If you have any other questions, please get in touch via the contact page.
There is also a another video below which shows you what to do with your marbled and mixed pieces.
