Retired now, and living in Mexico, my wife and I will be going on a hands-on tour in the Mexican highlands, focusing on textile design, in mid July.
The tour guide is someone we have toured with in the past. Marina has a PhD in archaeology, and grew up in Cuernavaca MX. (Her grandfather was also an archaeologist.) Her tour site is linked here.
This promises to be a fine educational and cultural experience for anyone who might be inclined. (I have no interest of gain in this mention. My motivation for sharing this event is a bit selfish: for the tour to happen, there must be a few more adventurers.)
Anyone wishing to research the general topic would do well to examine the book Maya Threads.
