Proper attire is mandatory. Please wear long pants and closed toed shoes. Natural fiber attire highly recommended for fire safety; students may wear synthetic attire, but they will be asked to watch and not participate in any hands on activities. This class is suitable for young students who are excellent at following directions and are comfortable around intense open flame. Recommended 12 and up.
