Established in 2002, Sone-Tu helps to preserve this unique traditional weaving culture, the visual language of the region. Before Sone-Tu began their work, backstrap weaving designs were in danger of being forgotten, as there was no written record. Sone-Tu brought master weavers out of retirement to assist with training a new generation in their historical weaving patterns and techniques.

Today, 52 patterns have been revived and over 100 weavers have gone through a rigorous training covering every aspect of this intricate art; it takes a woman several years to become a skilled master weaver. Each one of the silk and cotton masterpieces can take up to several weeks, if not months to complete. Today, Sone Tu experiments with new techniques and has even developed a new loom. Through the project, weavers are able to afford education for their children and grandchildren.

National Geographic documented one of these trainings in 2012.
