I'm really interested in PMC, and will be taking a class in the spring (soon as funds permit). But I haven't messed with any kind of clay since elementary school, so I wonder if it would be useful for me to practice with polymer clay first? It's much cheaper and doesn't require a kiln, so I'm thinking it would give me a way to get familiar with holding, kneading, shaping, and cutting clay before I take a class with the more expensive material.
Thoughts? Anyone work with both? How similar are they?
