Fund Raising Idea #63.....Day of Idea.....Face Painting at your tent.....you don't have to be a great artist to do face painting.  There is a lot of information available online about what type of paint and brushes you need as well as easy examples of what is fun to paint.  Most anything purple would be great, like a purple Relay Ribbon....or a star....The kids' would love it, and I bet some of the adults might have fun with it, too.  Have a poster with maybe 10 designs on it and let people choose.  It is up to you, what you decided to charge.
