Alternatives, a provider of developmental disability services, invited us to give several seminars for staff and clients at their arts festival:
We lectured several times to Framingham State University's advanced creativity classes:
Over the course of a school year we taught Zentangle in every class of Providence's MET School Peace Street campus.
We visited a Rhode Island Montessori school and worked with over 60 students between ages of 6 and 16. It was a great success across all age groups.
Everyone loved seeing their tiles together in a mosaic.
Even though we haven't visited everywhere (yet), there are Zentangle study groups forming in many places. Here's a picture of one in Singapore.
