I found this Fiber Arts tour in Provence, March17-31.  A very small group, just 6 people.  I am planning to go and have been in touch with the guide, Madeleine Vedel.  She has other ideas to add to the agenda-looks like fun. Her site is  https://www.cuisineprovencale.com

The link for the fiber tour is on the top of the page, Fiber Arts Tour.  
She also does cooking tours.
