Art Therapy sessions during supervision

I like to observe my supervisees facilitating an Art Therapy group which helps me when writing up their ATR paperwork, but due to my schedule, it's been hard to do that. So, on occasion, we have been able to run special Art Therapy sessions during our supervision time with volunteer patients. This has worked out well as we can all learn from each other. We have a diverse group of 19 Art Therapists with different backgrounds, and therapy styles.  It is also beneficial in that we can later discuss the patient art work and their process and all be familiar with them. This is also a good way to introduce Art Therapy to a patient who has never done it before.
