For average parties, two hours ensures that your guests get the best possible quality of artwork. For larger scale parties - We can give you a suggestion of how much time is needed to ensure that all your guests have a turn to get painted. On average, 8-12 faces can be painted per hour - and speed painting designs (20-25 faces per hour) are also an option for large scale events. Any overage in time due to more guests than expected will be added to the balance due after the event in 15 minute billing increments. But we will always give the host notice before this happens. Your time begins when we start painting, and we do not begin cleaning up until your time is up! Great service is extremely important to us. We do face painting because it brings joy and happiness to folks. So we promise to make your experience top notch!
