Regong barbola, also called guitang in Tibetan, is made by cutting colored brocade into pieces and joining them as a Buddhist image. A 2008 account describes the surface as shallow relief: seams and raised cloth contribute shape as well as color. In Nianduhu, the reporter found the artist Tashi working with a group of women students on brocade images, where the method could be seen in the pieces assembled by hand.

A Brocade Buddha for Labrang Monastery
A 2008 account describes Wutun artist Tashi and his women students making a 130-by-80-metre patchwork Buddha image for Labrang Monastery’s annual sunning of the Buddha.

A picture assembled from brocade
A hillside-sized image
The same account attributes a 130-by-80-metre patchwork image of Shakyamuni Buddha at Labrang Monastery to Tashi. It spread across a hillside for the monastery’s annual event, when a Buddha image is brought out for viewing. The size changes the work’s relationship to cloth: individual pieces form one figure meant to be seen across a slope. The account also notes smaller barbola hung in prayer halls, where a principal Buddha and two smaller figures make a compact composition. These are two scales of one textile form, described in a report from 2008.
