The craft projects in this class use sharp objects like scissors and messy supplies like glue and paint.  Parental supervision is strongly encouraged.  Certain tasks in this class will require adult assistance, such as tracing your child on a roll of paper.  Other tasks may require being outside in nature, so adult supervision would be necessary for some of them as well.
