Our PTO has a few fund-raisers each year. We have a primary, general PTO fund-raiser and other activity specific fund-raisers. For example,we have an Art Masterpiece program. We have an annual 'Art Walk' that is advertised as a fund-raiser for the Art Masterpiece program. Our problem is that this years 'Art Walk' was so successful, there are extra funds. Can these funds be used for other PTO activities, or do they need to be used as advertised? We had parents specifically request their donations be used only for Art Masterpiece. (Art Masterpiece is a line item in the PTO budget.)
