No! There is no requirement for you to have done things before that are similar. We welcome new people with all sorts of experiences and backgrounds.
The key thing is that you have a supportive and facilitative approach to leading workshops, and are able to reflect on and develop your practice.
You will want to be, or become, fairly comfortable with the sorts of activities, attitudes and skills that the workshops require and of course will be committed to Quaker beliefs and practices.
Reasonable travel claims (with receipts) will be fully reimbursed by the Kindlers.
You are responsible for your own subsistence (i.e. food and drink you consume en route), however, lunch etc. will usually be provided by the group hosting the workshop.
If overnight accommodation is required this will either be arranged by the group hosting the workshop, or, by agreement with the Clerk, covered by the Kindlers. Evening meal and breakfast in these circumstances will be covered as well
