Lori Craig's taken the class twice, if that helps at all. She felt she learned something new each time (or she was just saying it to make me feel better)
The classes are open first to store owners and teachers- people who will share what they learn with others. Then it opens to everyone if there is still space. These classes are NOT meant to be exclusive parties, rather, they are a low-key, fun but intensive class to learn and take the mystery out of using your Copics and see how you can do more with them.
They're technique based, so you don't make any finished cards (no time!). HTH!
