living in the KC area, where many national known quilters are located within about an hour drive at most, the presentations for a day & evening presentations run about $500-700, plus travel expenses. Workshops tend to run about the same for a class of 25+/-.
my guild has looked into bringing in some nationally known quilters from outside our area that would require airfare, extra baggage (those quilts weigh a ton!), hotel room and meals, and either a car rental or a member available to drive. That really adds to the cost.
