How many classes can I bring? For Painted Ceiling workshops we can accommodate one class each day. We can accommodate two classes each day for all other workshops. While one class is doing a facilitated workshop, the other class can follow one of our self-led trails to supplement the workshop content. Often, one of our volunteers is on hand to help out. At lunchtime, the groups swap activities. For our Tactile Tales workshop we can take one class in the morning and one in the afternoon.
