The following is my personal basic packing list for camping events. It is designed for Pennsic, and for smaller events I just pare it down. While everyone will have their own items that they need at Pennsic or any other camping event, this list can serve as a springboard.
When creating your own list, I recommend that you tour your home with pen and paper. In every room, ask yourself
What do I do in this room?
Would I want to be able to do that at a camping event?
What do I need to do that?
What would the camping equivalent of that be?
In this manner you should be able to develop a comprehensive list that will suit your specific needs.
candle lanterns and hangers
first aid kit
camp bed frame
two pillows and cases

modern clothing - one or two sets for going into town and the trip home

water bottle and case
personal kit - nail clippers, lotion, lip balm, etc.
